Procedure

Triethylamine (0.10 mL) and methyl chloroformate (24 μL) were added consecutively to (S)-6-(2-hydroxy-2-methyl-propyl)-6-phenyl-3-[(S)-1-(4-piperidin-4-yl-phenyl)-ethyl]-[1,3]oxazinan-2-one (0.12 g) dissolved in dichloromethane (5 mL) at room temperature. The resulting solution was stirred at room temperature overnight and then diluted with dichloromethane. The resulting solution was washed with water and brine and dried (Na2SO4). After removal of the solvent, the residue was purified by chromatography on silica gel (CH2Cl2/MeOH 99:1→90:10) to afford the title compound as a foam-like solid.
