実験手順: 3.00 g (12.81 mmol) of ethyl 8-hydroxy-2,6-dimethylimidazo[1,2-a]pyridine-3-carboxylate Example 17A, 3.27 g (14.1 mmol) of 2-(bromomethyl)-1,3,4-trifluorobenzene and 9.18 g (28.17 mmol) of caesium carbonate were initially charged in 183 ml of dry DMF and heated for 30 min in an oil bath warmed to 60° C. About 1.8 l of water were added to the reaction mi×ture, the mixture was stirred for 30 min and the solid was filtered off, washed with water and dried under reduced pressure. This gave 5.07 g of the title compound (99% of theory; purity about 96%). heated for 30 min in an oil bath the solid was filtered off washed with water dried under reduced pressure

Water was added to quench the reaction and it was extracted with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo to yield 2,2-dimethyl-3-(2,3,6-trifluorophenyl)propanenitrile (34) as a white solid. stirred for 1.5 h to quench the reaction and it was extracted with ethyl acetate The combined organic layers were dried over sodium sulfate filtered concentrated in vacuo
