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 (100 mg, 0.15 mmol) and cyclopropylsulfonamide (24 mg, 0.20 mmol) as described in the general procedure above. Flash chromatography (2% methanol/methylene chloride) gave 55 mg (53%) of [4-cyclopropanesulfonylaminocarbonyl-18-(isoquinolin-1-yloxy)-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: 1H NMR (500 MHz, CD3Cl3) δ 0.89–0.95 (m, 1H), 1.03–1.16 (m, 3H), 1.22 (s, 9H), 1.18–1.48 (m, 8H), 1.78 (m, 1H), 1.87 (m, 1H), 1.94 (m, 1H), 2.29 (q, J=9.0 Hz, 1H), 2.56 (m, 1H), 2.67 (dd, J=7.9 Hz, 2.7 Hz, 2H), 2.90 (m, 1H), 4.04 (dd, J=11.3 Hz, 4.0 Hz, 1H), 4.29 (m, 1H), 4.61 (m, 2H), 4.97–5.03 (m, 2H), 5.70 (m, 1H), 5.94 (s, 1H), 6.67 (s, 1H), 7.25 (m, 1H), 7.47 (t, J=7.3 Hz, 1H), 7.64 (t, J=7.3 Hz, 1H), 7.72 (d, J=7.9 Hz, 1H), 7.97 (d, J=5.8 Hz, 1H), 8.17 (d, J=8.5 Hz, 1H), 10.20 (s, 1H). LC-MS (Method A, retention time: 3.67 min), MS m/z 696 (M++1).
