실험 절차

A mixture of crude (S)-1-[{(9H-Fluoren-9-yl)methoxy}carbonyl]piperidine-2-carboxylic acid (0.75 g, 2.21 mmol), tert-butyl[2-(aminomethyl)-4-chlorobenzyl]carbamate (0.52 g, 1.93 mmol), HOBT (0.26 g, 1.93 mmol), and EDC.HCl (0.48 g, 2.51 mmol) in DMF (5 mL) was stirred under nitrogen at room temperature for 16 h. The reaction mixture was quenched with water (20 mL) and diluted with EtOAc (50 mL). The organic layer was washed sequentially with saturated aqueous NaHCO3 solution (50 mL) and brine solution (50 mL), dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by reverse phase combiflash column chromatography (C18; eluent: 10-100% acetonitrile:water) to afford the title compound (0.89 g) as a white solid.
