Procedure

To 15 mL of an N,N-dimethylformamide solution containing 1.5 g of 1-(trifluoroacetyl)piperidine-4-amine hydrochloride, 1.4 g of 2-bromo-N-(pyridin-2-yl)acetamide and 1.8 g of potassium carbonate were added, and the mixture was stirred at room temperature for 4 hours. The reaction mixture was added with ethyl acetate and water. The organic layer was separated, and the aqueous layer was extracted with ethyl acetate. The organic layer and the extract were combined, the resultant solution was washed sequentially with water and an aqueous saturated sodium chloride solution and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue thus obtained was purified by silica gel column chromatography [eluent; chloroform:methanol=10:1] to obtain 1.1 g of a light brown oily substance, N-(pyridin-2-yl)-N2-(1-(trifluoroacetyl)piperidin-4-yl)glycinamide.
