Add 1M lithium aluminum hydride in THF (7.3 mL) to benzo[b]thiophene-6-carbonitrile (0.6 g, 3.6 mmol) at 0° C. in THF (36 mL). After 15 h at ambient temperature, cool to 0° C. and add sequentially water (1.82 mL), 2N aqueous NaOH (1.82 mL) and water (2.60 mL). Filter the solid and evaporate the filtrate to obtain the crude amine. Purify by SCX chromatography. Rinse the column with methanol, add a solution of the crude amine in methanol, wash the column with methanol and then elute with 1N ammonia in methanol. Concentrate in vacuo to give the title compound (0.55 g, 92%).
