実験手順
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 2,3-dihydro-1,4-benzodioxine-6-carbonyl chloride (105 mg, 0.53 mmol). The final trituration (diethyl ether/hexane) and filtration gave 50 mg (39%) of 18-(2,3-dihydro-1,4-benzodioxine-6-carbonyloxy)-14-tert-butoxycarbonylamino-4-cyclopropylsulfonylaminocarbonyl-2,15-dioxo-3,16-diazatricyclo-[14.3.0.04,6]-nonadec-7-ene as a white powder: 99.5% pure (HPLC), MS m/z 729 (M−H)−, HRMS: calcd. 748.3228 and found 748.3220 (M+NH4)+, mp 199-201° C.
