Reaction Steps

Prepared from 14-tert-butoxycarbonylamino-18-(isoquinolin-1-yloxy)-2,15-dioxo-3,16-diaza-tricyclo[14.3.0.04,6]-nonadec-7-ene-4-carboxylic acid etherate (105 mg, 0.177 mmol) and 1-methyl-cyclopropanesulfonic acid amide (31 mg, 0.23 mmol, prepared as described above). Flash chromatography (2% methanol/methylene chloride) gave 73 mg (58%) of [18-(isoquinolin-1-yloxy)-4-(1-methyl-cyclopropanesulfonylaminocarbonyl)-2,15-dioxo-3,16-diaza-tricyclo[14.3.0.04,6]nonadec-7-en-14-yl]-carbamic acid tert-butyl ester as a white powder: LC-MS (Method A, retention time: 3.50 min), MS m/z 710 (M++1).
