反応手順
A mixture of 860 mg of 8-(cyclohexylmethoxy)-2-methylimidazo[1,2-a]pyridine-3-carboxylic acid, 992 mg of 1-benzyl-4-methylpiperidine-4-amine dihydrochloride, 170 mg of O-(7-azabenzotriazole-1-yl)-N,N,N′,N′,-tetramethyluronium hexafluorophosphate, 3 mL of diisopropylethylamine, and 10 mL of DMF was stirred for 1 day. To the reaction mixture were added water and ethyl acetate to carry out a layer separation operation. The organic layer was washed with water and saturated brine in this order, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the obtained residue was purified by silica gel column chromatography to obtain 1.25 g of N-(1-benzyl-4-methylpiperidin-4-yl)-8-(cyclohexylmethoxy)-2-methylimidazolo[1,2-a]pyridine-3-carboxamide.
