Reaction Steps
Prepared by way of method I using 18-hydroxy-14-tert-butoxycarbonylamino-4-cyclopropylsulfonylaminocarbonyl-2,15-dioxo-3,16-diazatricyclo[14.3.0.04,6]-nonadec-7-ene (100 mg, 0.175 mmol) and 4-chlorobenzoyl chloride (45 μL, 0.35 mmol). The final trituration (diethyl ether/hexane) and filtration gave 68 mg (55%) of 18-(4-chlorobenzoyloxy)-14-tert-butoxycarbonylamino-4-cyclopropylsulfonylaminocarbonyl-2,15-dioxo-3,16-diazatricyclo-[14.3.0.04,6]-nonadec-7-ene as a white powder: 98.5% pure (HPLC), MS m/z 705 (M−H)−, HRMS: calcd. 707.2518 and found 707.2499 (M+H)+, mp 143-145° C.
