Participants

Reaction Steps

The title compound was prepared according to the general procedure for the synthesis of N-Aryl-benzenesulfonamides previously described using 116 mg of (2-amino-5-chloro-phenyl)-pyridin-4-yl-methanone and 100 mg of 3-cyano-benzenesulfonyl chloride. 1H-NMR (400 MHz, CDCl3): δ 7.36 (d, 1H, J=2.4 Hz), 7.57-7.62 (m, 4H), 7.68 (d,1H, J=8.8 Hz), 7.80 (m,1H), 8.04 (m, 2H), 8.90 (dd, 2H, J=4.8 Hz, 1.6 Hz), 10.3 (b, 1H). MS: m/z 398.8 (M++1).
