Participants

Reaction Steps

By using a method similar to the method of Example 532, combine 2-(2-nitro-phenylamino)-benzo[b]thiophene-3-carbonitrile (5.0 g, 17.0 mmol) and Tin(II) chloride (9.65 g, 51.0 mmol) in a mixed solvent of EtOH (50 mL) and 5.0 N HCl (50 mL), heat the suspension to reflux for 3 hours, cool to RT. The title compound 4.65 g (yield 91%) is obtained as a yellow solid by suction filtration. Mass spectrum: ACPI (m/e): 266.0 ((M+1-HCl); 1H NMR (300 MHz, DMSO-d6) ppm: 11.7 (br, 1H), 10.00 (br, 1H), 9.10 (br, 2H), 7.90–7.85 (m, 1H), 7.72–7.65 (m, 1H), 7.48–7.38 (m, 1H), 7.35–7.28 (m, 1H), 7.22–6.98 (m, 4H).
