Product 1

HCID 7244538318-(3,4-Methylenedioxybenzoyloxy)-14-tert-butoxycarbonylamino-4-cyclopropylsulfonylaminocarbonyl-2,15-dioxo-3,16-diazatricyclo-[14.3.0.04,6]-nonadec-7-eneYield 35.1%

Procedure

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 3,4-methylenedioxybenzoyl chloride (65 μL, 0.35 mmol). The final trituration (diethyl ether/hexane) and filtration gave 44 mg (35%) of 18-(3,4-methylenedioxybenzoyloxy)-14-tert-butoxycarbonylamino-4-cyclopropylsulfonylaminocarbonyl-2,15-dioxo-3,16-diazatricyclo-[14.3.0.04,6]-nonadec-7-ene as a white powder: 98.6% pure (HPLC), MS m/z 717 (M+H)+, HRMS: calcd. 717.2806 and found 717.2789 (M+H)+, mp 153-155° C.
