실험 절차

A solution of methyl 1-{[2-[(tert-butoxycarbonyl)amino]-2-(3,5-difluorophenyl)propyl]amino}cyclohexanecarboxylate from Step E (280 mg, 0.657 mmol) in EtOAc (5 mL) at 0° C. was saturated with HCl (g). The reaction mixture was aged at 0° C. for 30 min, then poured carefully into saturated aqueous NaHCO3 (10 mL). The resulting mixture was extracted with EtOAc (2×15 mL). The combined organic extracts were dried over Na2SO4, filtered, and concentrated in vacuo to give the title compound. MS: m/z=327 (M+1).
