Procedure
The title compound was prepared according to the general procedure for the synthesis of N-Aryl-benzenesulfonamides previously described using 117 mg of (2-Amino-5-chloro-phenyl)-pyrazin-2-yl-methanone and 116 mg of 4-tert-butyl-benzenesulfonyl chloride. 1H-NMR (400 MHz, CDCl3): δ 1.24 (s, 9H), 7.38 (dm, 2H, J=6.8 Hz), 7.50 (dd, 1H, J=9.2 Hz, 1.6 Hz), 7.70 (m, 2H), 7.76 (m, 1H), 7.80 (m, 1H), 8.62 (m, 1H), 8.77 (m, 1H), 9.06 (m, 1H), 10.37 (s, 1H). MS: m/z 430.0 (M++1).
