実験手順

tert-Butyl (3S,5R)-3-[(2-methylpropyl)amino]-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (100 mg) and diisopropylethylamine (0.095 ml) were dissolved in dichloromethane (3 ml), a solution of 7-chlorothieno[3,2-b]pyridine-6-carbonyl chloride (70 mg) in dichloromethane (2 ml) was added dropwise, and the mixture was stirred at room temperature for 1 hr. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate and the solvent was evaporated under reduced pressure. The residue was subjected to silica gel column chromatography, and the fraction eluted with ethyl acetate was concentrated under reduced pressure to give the object compound (120 mg).
