実験手順

Crude 4-[(2R)-2-(4-Bromophenyl)-2-chloroethyl]morpholine (34.5 g) was dissolved in 200 mL of EtOH at room temperature with magnetic stirring. The resulting solution was cooled to 0° C. and treated with 71 ml of MeNH2 (33 wt % in EtOH) under N2. The reaction flask was capped by a rubber septum, and the reaction mixture was maintained at room temperature for 48 h. The reaction mixture was concentrated, and the residue was partitioned between EtOAc and sat NaHCO3(aq). The organic layer was washed by brine, dried over MgSO4, and filtered. The filtrate was concentrated to yield the title compound as a yellow solid (31.6 g, 93%). MS (ES) m/e 300, 301 [M+H]+.
