Reaction Steps

3-Bromo-2-methyl-6-[3-(3,4,5-trichlorophenyl)-3-(trifluoromethyl)pyrrolidin-1-yl]-pyridine (3.3 g) and copper cyanide (I) (0.65 g) were added to N-methyl-2-pyrrolidinone (10 ml). The mixture was heated for 4 hours at 200° C. using a microwave reactor (trade name: INITIATOR™, manufactured by Biotage). Upon the completion of the reaction, the reaction mixture was diluted with ethyl acetate and the precipitate was filtered off through a short silica gel layer. The filtrate was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography to obtain 2-methyl-6-[3-(3,4,5-trichlorophenyl)-3-(trifluoromethyl)pyrrolidin-1-yl]nicotinonitrile (1.1 g).
