Participants

Reaction Steps

Prepared by a similar procedure to that described as in Step D for example 22 from the 2-bromo-5-methylsulfonyl-3-nitro-thiophene (148 mg, 0.52 mmol) and 2,4-dichlorobenzenethiol (100 mg, 0.56 mmol) to afford the title product as a solid (50 mg, 25% yield). 1H NMR (400 MHz, d6-DMSO) δ: 8.35 (1H, s), 8.10 (1H, m), 8.20 (1H, m), 7.74 (1H, m), 3.42 (3H, s). MS m/z: 381.81 [M+H]+.
