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 pyrazinecarbonyl chloride (75 mg, 0.53 mmol). The final trituration (diethyl ether/hexane) and filtration gave 62 mg (52%) of 18-(pyrazinecarbonyloxy)-14-tert-butoxycarbonylamino-4-cyclopropylsulfonylaminocarbonyl-2,15-dioxo-3,16-diazatricyclo-[14.3.0.04,6]-nonadec-7-ene as a white powder: 98.8% pure (HPLC), MS m/z 673 (M−H)−, HRMS: calcd. 675.2812 and found 675.2792 (M+H)+, mp 150-152° C.
