| Reactant | tert-butyl N-[4-(cyclopropylsulfonylcarbamoyl)-18-hydroxy-2,15-dioxo-3,16-diazatricyclo[14.3.0.04,6]nonadec-7-en-14-yl]carbamate | HCID 68797769 | — |
| Product | HCID 72445382 | HCID 72445382 | 37% |
Reaction Steps
Prepared by way of method II 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-cyanobenzoyl chloride (87 mg, 0.53 mmol). The final trituration (diethyl ether/hexane) and filtration gave 45 mg (37%) of 18-(4-cyanobenzoyloxy)-14-tert-butoxycarbonylamino-4-cyclopropylsulfonylaminocarbonyl-2,15-dioxo-3,16-diazatricyclo-[14.3.0.04,6]-nonadec-7-ene as a white powder: 99.0% pure (HPLC), MS m/z 696 (M−H)−, HRMS: calcd. 715.3125 and found 715.3147 (M+NH4)+, mp 164-166° C.
