Procedure

To a solution of tert-butyl (2S)-4-{4-[({4-[(4-chlorophenyl)sulfonyl]cyclohexyl}carbonyl)(methyl)amino]-2-methylbenzyl}-2-methylpiperazine-1-carboxylate (80.2 mg, 0.13 mmol) synthesized in (10D) in dichloromethane (1 mL), trifluoroacetic acid (10 mL) was added at room temperature, and the resulting mixture was stirred at room temperature for 30 minutes. The solvent was distilled off under reduced pressure, and the obtained residue was purified by NH silica gel column chromatography (ethyl acetate:methanol=100:0 to 90:10 (v/v)), whereby the title compound was obtained as an oil (50.1 mg, yield: 100%).
