反応手順

To a stirred solution of (R)-(+)-1-(4-bromophenyl)ethylamine (0.5 g, 2.49 mmol) in anhydrous CH2Cl2 was added methyl isocyanate (0.15 mL, 2.49 mmol). The resulting solution was stirred at 25° C. overnight. CH2Cl2 was evaporate and residue partitioned between EtOAC and 1 N HCl. The organic layer was washed with H2O, brine and dried over Na2SO4. The solvent was removed in vacuo and the residue was purified by flash column chromatography (80% EtOAc in hexanes) to provide the desired product (0.60 g, 94%) as a white solid.
