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 benzoyl chloride (61 μL, 0.53 mmol). The final trituration (diethyl ether/hexane) and filtration gave 56 mg (48%) of 18-benzoyloxy-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: 99.0% pure (HPLC), MS m/z 673 (M−H)−, HRMS: calcd. 675.2700 and found 675.2709 (M+H)+, mp 135-137° C.
