반응 단계
To a solution of 600 mg of 8-(cyclohexylmethoxy)-2-methylimidazo[1,2-a]pyridine-3-carboxylic acid in 10 ml of DMF were added 500 mg of tert-butyl (3S)-3-aminopiperidine-1-carboxylate, 518 mg of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride, and 366 mg of 1-hydroxybenzotriazole, followed by stirring overnight. 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, dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography to obtain 808 mg of tert-butyl (3S)-3-({[8-(cyclohexylmethoxy)-2-methylimidazo[1,2-a]pyridin-3-yl]carbonyl}amino)piperidine-1-carboxylate.
