実験手順

Combine the amine (0.323 g, 0.838 mmol), (5-tert-butyl-isoxazol-3-yl)-carbamic acid 2,2,2-trichloro-ethyl ester (0.291 g, 0.922 mmol) and triethylamine (0.128 mL, 0.922 mmol) in DMSO (10 mL). Heat the mixture to 70° C., stir overnight, and cool to room temperature. Extract the mixture with ethyl acetate versus water. Wash the organic layer with saturated aqueous saturated sodium chloride. Dry the resulting organics over magnesium sulfate, filter, and concentrate. Purify by column chromatography (ethyl acetate→10% methanol in dichloromethane→10% 2 M NH3 in MeOH in dichloromethane) to afford product (0.057 g, 11%, two steps). MS(ES), m/z 552 (M+1).
