Reaction Steps

12.5.g (0.74 mol) of gaseous ammonia were passed into a stirred mixture of 40 g (0.184 mol) of 3-chloro-2,6-difluoro-5-trifluoromethylpyridine in 200 ml of ethanol in the course of 45 minutes at 50°-60 C. After the reaction mixture had been stirred for 11/2 hours at 55° C., it was cooled and concentrated. The residue was stirred in water, filtered off with suction and dried, giving 36.7 g (93% of theory) of the title compound of m.p. 101°-103° C.
