Definitions
- the present invention relates to a process for the preparation of a derivative of the racemic 2-amino-naphthyridine of formula:
- the active entity or eutomer is the dextrorotatory isomer.
- the dextrorotatory isomer of the product of formula (II) can also be obtained by cyclization of the dextrorotatory isomer of the product of formula (I) by means of thionyl chloride, optionally operating in the presence of a condensing agent such as imidazole or pyridine in an organic solvent such as methylene chloride.
- a condensing agent such as imidazole or pyridine
- the dextrorotatory isomer of the product of formula (I) can be obtained by resolution of the corresponding racemic by means of a chiral base. To this end, it is particularly advantageous to carry out the succession of the following operations: 1) formation of a salt with a chiral base or a chiral acid,
- the dextrorotatory isomer of the product of formula (I) After displacement of its salt with cinchonine, the dextrorotatory isomer of the product of formula (I), which is mainly found in the filtration mother liquors of the levorotatory salt, is transformed into an insoluble salt with cinchonidine.
- the dextrorotatory isomer of the product of formula (I) is displaced from its salt by means of a strong acid such as hydrochloric acid.
- the product of racemic formula (I) can be obtained by opening the pyrrolidinone ring of a product of racemic formula (H) in basic medium.
- the pyrrolidinone cycle is opened using a mineral base at a temperature between 0 and 50 ° C and, preferably, between 0 and 30 ° C.
- the levorotatory isomer of the product of formula (II) is transformed into a racemic product of formula (I) by the action of a mineral base such as sodium hydroxide in a basic organic solvent such as pyridine at a temperature comprised between 0 and 50 ° C and preferably close to 20 ° C.
- a mineral base such as sodium hydroxide
- a basic organic solvent such as pyridine
- the levorotatory isomer of the product of formula (Et) can be obtained by cyclization of the levorotatory isomer of the product of formula (I) by means of thionyl chloride in the presence of a condensing agent such as imidazole or pyridine by operating in an organic solvent such as methylene chloride.
- the levorotatory isomer of the product of formula (I) can be obtained, for example, from the mother liquors of crystallization of the salt of the dextrorotatory isomer of the product of formula (I) with the (+) - ephedrine.
- the levorotatory isomer of the product of formula (I) is obtained by displacement of its salt according to the usual methods after concentration of the ethanolic mother liquors of crystallization.
- the chiral base used [(-) -é ⁇ hédrine] can also be recovered.
- the suspension obtained is filtered.
- the precipitate is washed with 5 times 525 cm3 of distilled water and then dried under reduced pressure (15 mm of mercury; 2 kPa) for 16 hours at 60 ° C.
- the levorotatory isomer of [(7-chloro-naphthyridine-1,8 yl) -2] -2 (5-methyl-2-oxo-hexyl) -3 isoindolinone-1 can be obtained in the following way:
- the organic phase is concentrated under atmospheric pressure to a volume of approximately 2200 cm3.
- the product obtained is transformed into the levorotatory isomer of [(7-chloro-naphthyridine-1,8 yl-2) -2 (5-methyl-2-oxo-hexyl) -3 isoindolinone-1 using thionyl chloride (96.9 g) in the presence of imidazole (222.8 g).
- the chloromethylenic phase (2614 g) is distilled under atmospheric pressure in the presence of 1000 cm3 of ethanol.
- EXAMPLE 3 120 g of salt of ⁇ [(7-chloro-naphthyridin-1,8 yl-2) amino] -2 methyl-6-oxo-3 heptyl ⁇ -2 benzoic acid are dissolved with (+) - ephedrine in 2350 cm3 of methylene chloride. The organic phase is washed with 400 cm3 of 0.5N hydrochloric acid and then 400 cm3 of water. The combined aqueous phases are treated under the conditions of Example 2 to give an ethanolic solution of (+) - ephedrine which is used as it is in a new salification operation.
