A mixture solution of 3-bromo-2-nitrobenzo[b]thiophene (14 g, 54 mmol), aniline (14 ml, 154 mmol) and triethylamine (11 ml, 79 mmol) in DMF (150 ml) was heated at 120° C. for 30 min before quenching with water. The solid was isolated by filtration, washed with water and recrystallized from DCM/hexane to yield 2-nitro-N-phenylbenzo[b]thiophen-3-amine (14 g, 96%) as a yellow solid.
