PROCEDURE

实验过程

Prepared by way of method I using 18-hydroxy-14-tert-butoxycarbonylamino-4-cyclopropylsulfonylaminocarbonyl-2,15-dioxo-3,16-diaza-12-oxatricyclo[14.3.0.04,6]-nonadec-7-ene (100 mg, 0.175 mmol) and 4-phenoxybenzoyl chloride (111 mg, 0.53 mmol). The final trituration (diethyl ether/hexane) and filtration gave 16 mg (12%) of 18-(4-phenoxybenzoyloxy)-14-tert-butoxycarbonylamino-4-cyclopropylsulfonylaminocarbonyl-2,15-dioxo-3,16-diaza-12-oxatricyclo-[14.3.0.04,6]-nonadec-7-ene as a white powder: 97.5% pure (HPLC), MS m/z 765 (M−H)−, HRMS: calcd. 784.3228 and found 784.3208 (M+NH4)+, mp 207-209° C.
