Reaction Steps

2-aminopyridine in an amount of 0.94 g (10 mmol) was dissolved in 20 mL of tetrahydrofuran (THF), following which 2.84 g (20 mmol) of ethyl trifluoroacetate and 1.22 g (10 mmol) of dimethylaminopyridine were added, and refluxing was carried out for 22 hours. THF was removed by distillation, following which purification was carried out with a silica gel column (developing solvent: 4:1 solution of hexane and ethyl acetate), giving 0.26 g of 2,2,2-trifluoro-N-(pyridin-2(1H)-ylidene)acetamide (yield, 13.7%).
