Participants

Reaction Steps

Example 217 was synthesized in a similar manner to Example 212, except that 1-chloro-4-fluoro-N-(4-methoxybenzyl)-N-(pyrimidin-4-yl)isoquinoline-6-sulfonamide (Intermediate QQQ) and (4-chloro-2-methoxyphenyl)boronic acid were used as the coupling partners. The final compound was purified via column chromatography (12 g silica gel column, gradient elution 25 to 100% EtOAc:Heptane) to afford 1-(4-chloro-2-methoxyphenyl)-4-fluoro-N-(pyrimidin-4-yl)isoquinoline-6-sulfonamide as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm=8.70 (s, 1H), 8.58 (d, J=10.4 Hz, 2H), 8.21 (s, 1H), 8.05 (d, J=9.1 Hz, 1H), 7.78 (d, J=8.6 Hz, 1H), 7.40-7.30 (m, 2H), 7.19 (dd, J=2.0, 8.0 Hz, 1H), 7.10-6.80 (m, 1H), 3.67 (s, 3H). m/z (ESI) 445.2 (M+H)+.
