실험 절차
To a solution of ethyl piperazine-1-carboxylate (1.0 g, 6.32 mmol) in dichloromethane (30 ml) was added m-tolylisocyanate (0.90 mg, 6.95 mmol). The reaction mixture was stirred at room temperature for 2 hours. The mixture was diluted with dichloromethane and washed with water, brine and dried over Na2SO4. After removing the solvents, the residue was purified by chromatography on silica gel (CH2Cl2/MeOH 50:1) to yield the title compound as a white solid (1.6 g, 87%).
