Reaction Steps

The procedure in Example 318: part e was followed using 5-methylsulfanyl-4-{3-nitro-4-[(pyridin-2-ylmethyl)-amino]-benzenesulfonyl}-thiophene-2-carboxylic acid methyl ester ((Example 264: step c) 41 mg, 0.08 mmol), iron (110 mg, 2 mmol), and EtOH/aq. AcOH, followed by treatment with formic acid to yield the title compound. 1H-NMR (CD3OD): δ 8.50 (m, 1H), 8.42 (s, 1H), 8.08 (m, 1H), 7.97 (d, 1H, J=2.5 Hz), 7.85 (m, 1H), 7.72 (m, 1H), 7.71 (dt, 1H, J=1.9, 7.7 Hz), 7.57 (m, 1H), 7.29 (m, 1H), 7.22 (d, 1H J=7.8 Hz), 6.95 (d, 1H, J=9.0 Hz), 5.57 (s, 2H), 3.82 (s, 3H), 2.56 (s, 3H).
