Versuchsvorschrift

In 5 ml of chloroform was dissolved 500 mg of ethyl 2-[6-chloro-2-(2,4-difluorophenylamino)-5-fluoronicotinoyl]acetate, and 260 mg of 3-aminopyrrolidine dihydrochloride and 500 mg of triethylamine were added thereto, after which the resulting mixture was subjected to reaction under reflux for 1.5 hours. Subsequently, the reaction mixture was added to a mixture of 5 ml of chloroform and 5 ml of water, and the organic layer was separated, washed successively with 5 ml of water and 5 ml of saturated aqueous sodium chloride solution, and then dried over anhydrous magnesium sulfate. The solvent was removed by distillation under reduced pressure, and to the crystalline material thus obtained was added 2 ml of diisopropyl ether, after which crystals were collected by filtration to obtain 480 mg (yield 84.7%) of ethyl 2-[6-(3-amino-1-pyrrolidinyl)-2-(2,4-difluorophenylamino)-5-fluoronicotinoyl]acetate having a melting point of 140°-142° C.
