1-Sulfonylurea → N-({[4-(6-amino-7-fluoro-1-oxoisoquinolin-2(1H)-yl)phenyl]amino}carbonyl)-5-propylthiophene-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-propylthiophene-2-sulfonic acid amide to give N-({[4-(6-amino-7-fluoro-1-oxoisoquinolin-2(1H)-yl)phenyl]amino}carbonyl)-5-propylthiophene-2-sulfonamide. ES-MS (M+H)+=515.1; 1H-NMR (DMSO-d6) δ (ppm): 9.06-9.00 (s, 1H), 7.66-7.62 (d, J=12.4 Hz, 1H), 7.62-7.58 (d, J=3.7 Hz, 1H), 7.48-7.42 (m, 2H), 7.32-7.26 (m, 2H), 7.24-7.20 (d, J=7.3 Hz, 1H), 6.96-6-90 (d, J=3.6 Hz, 1H), 6.74-6.66 (d, J=8.4 Hz, 1H), 6.58-6.48 (bs, 1H), 6.50-6.46 (d, J=7.3 Hz, 1H), 2.84-2.76 (m, 5H), 1.68-1.56 (tq, J=7.3, 7.6 Hz, 2H), 0.94-0.86 (t, J=7.3 Hz, 3H).
