실험 절차

To a solution of 3-piperidinemethanol (5.0 g, 43.4 mmol), 1-(4-chlorophenyl)-1-cyclobutanecarboxylic acid (9.14 g, 43.4 mmol), and diisopropylethylamine (11.22 g, 86.8 mmol) in dichloromethane (100 mL) at 0° C. was added PyBroP® (22.26 g, 47.8 mmol). The reaction was stirred at 0° C. for 1 h and then at room temperature for 4 h. The reaction mixture was washed successively with water, 1 N HCl, water, sat. sodium bicarbonate solution, and water (100 mL each). The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated by rotary evaporation. The residue was purified by chromatography on silica gel, eluting with dichloromethane/methanol (96:4) to give 5.8 g of the amide 1 as a thick gum.
