Participants

Reaction Steps

The title compound was prepared in a manner similar to that described in Example 1 by replacing 4-fluoro-3-nitrophenylsulfonyl chloride with 2,3,4-trifluorophenylsulfonyl chloride and replacing p-anisidine with 3-chloro-4-methoxyaniline. 1H-NMR (CDCl3): δ 7.56 (1H, m), 7.17 (1H, d, J=2.0 Hz), 7.02 (1H, m), 6.98 (1H, dd, J=9.0 and 2.0 Hz), 6.78 (1H, d J=9.0 Hz), 6.72 (1H, br s), 3.83 (3H, s). MS(EI): 352 (7, M+), 351 (20), 156 (100). Anal. Calcd. for C13H9ClF3NO3S: C, 44.39; H, 2.58; N, 3.98; S, 9.11. Found: C, 44.31; H, 2.58; N, 3.96; S, 9.08.
