Participants

Reaction Steps

The title compound was prepared essentially according to the method of Example 4, but using 5-Chloro-2-(1H-tetrazol-5-yl)aniline (1.0 mmol) and benzo[b]thiophene-2-carbonyl chloride. After precipitation, the product was further purified by recrystallization in ethanol to yield the desired product (19.6 mg, 5%). 1H NMR (400 MHz, d6-DMSO): δ 8.61 (s, 1H), 8.31 (s, 1H), 8.09 (m, 3H), 7.53 (m, 3H). MS (EI) for C16H10ClN5OS: 355.8 (M+H).
