Procedure
Prepared according to the procedure described for example 70 from 5-[(3,5-dichloro-4-pyridyl)sulfanyl]-4-nitro-thiophene-2-carboxylic acid (150 mg, 0.43 mmol) and 2,2,6,6-tetramethylpiperidin-4-amine (81.0 mg, 0.51 mmol). The title compound was obtained as a solid (35.0 mg, 17% yield). 1H NMR (400 MHz, d6-DMSO) δ: 8.99 (2H, m), 8.81 (1H, m), 8.47 (1H, s), 7.81 (1H, m), 4.18 (1H, m), 1.96 (2H, m), 1.51 (2H, m), 1.39 (12H, m). MS m/z: 487.25, 489.27 [M+H]+.
