1-Sulfonylurea → N-({[4-(6-amino-7-fluoro-1-oxoisoquinolin-2(1H)-yl)phenyl]amino}carbonyl)-5-difluoromethylthiophene-2-sulfonamide

Participants

Reaction Steps

An analogous sulfonylurea coupling and de-protection procedure to that described in Example 29 was performed on [2-(4-Amino-phenyl)-7-fluoro-1-oxo-1,2-dihydro-isoquinolin-6-yl]-methyl-carbamic acid tert-butyl ester (Example 9) and 5-difluoromethyl-thiophene-2-sulfonic acid amide to give N-({[4-(6-amino-7-fluoro-1-oxoisoquinolin-2(1H)-yl)phenyl]amino}carbonyl)-5-difluoromethylthiophene-2-sulfonamide. ES-MS (M+H)+=523.1; 1H-NMR (DMSO-d6) δ (ppm): 8.70-8.64 (s, 1H), 7.66-7.60 (d, J=12.4 Hz), 7.56-7.48 (m, 2h), 7.38-7.10 (t, J=55.3 Hz, 1H), 7.36-7.32 (m, 1H), 7.28-7.24 (m, 1H), 7.22-7.18 (d, J=7.7 Hz, 1H), 7.12-7.06 (m, 2H), 6.72-6.66 (d, J=8.4 Hz, 1H), 6.52-6.46 (bs, 1H), 6.48-6.44 (d, J=7.3 Hz, 1H), 2.81-2.77 (bd, J=4.7 Hz, 3H).
