Product 1

HCID 120168761-[(3-Hydroxy-4-methoxyphenyl)aminosulfonyl]-2,3,4-trifluorobenzene

Procedure

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-hydroxy-4-methoxyaniline. 1H-NMR (CDCl3): δ 7.55 (1H, m), 7.00 (1H, m), 6.70 (2H, m), 6.60 (2H, m), 5.61 (1H, s), 3.83 (3H, s). Anal. Calcd. for C13H10F3NO4S: C, 46.85; H, 3.02; N, 4.20; S, 9.62. Found: C, 46.79; H, 3.03; N, 4.24; S, 9.53.
