실험 절차

Dissolve methyl 4-benzyl-3-methyl-5-oxomorpholine-3-carboxylate in THF (10 volumes) and cool to 0° C. Add borane dimethylsulfide complex (1.5 eq) and allow to warm to room temperature. Add water (5 volumes) followed by EtOAc (10 volumes). Separate the organic layer, wash with saturated aqueous NaCl, dry over sodium sulfate, filtered, and concentrate to give methyl 4-benzyl-3-methylmorpholine-3-carboxylate.
