Reaction Steps

The title compound was prepared in a manner similar to that described in Example 1 by replacing p-anisidine with 3-hydroxy-4-methoxyaniline and replacing 4-fluoro-3-nitrophenylsulfonyl chloride with 3,5-dichloro-2,4,6-trifluorophenylsulfonyl chloride (Example B). 1H-NMR (CDCl3): δ 6.88 (1H, br s), 6.7-6.8 (3H, m), 5.66 (1H, s), 3.85 (3H, s), MS(EI): 402 (15, M+), 401 (20), 138 (100). Anal. Calcd. for C13H8Cl2F3NO4S: C, 38.83; H, 2.00; N, 3.48; S, 7.97. Found: C, 38.66; H, 1.97; N, 3.39; S, 7.86.
