Reaction Steps

Sodium borohydride (9.4 mg, 0.223 mmol) was added to a mixture of N-{4-[4-amino-7-(2-formylthien-3-yl)thieno[3,2-c]pyridin-3-yl]-2-methoxyphenyl}-1-methyl-1H-indole-2-carboxamide (40.0 mg, 0.0743 mmol) in N, N-dimethylforamide (5 mL) under an atmosphere of nitrogen gas. The solution was stirred for 20 hours at room temperature after which it was diluted with methylene chloride and was washed with water (10 mL) and brine (10 mL). The organics were dried over magnesium sulfate and the solvent was removed in vacuo. The product was purified via flash chromatography to furnish the title compound as a yellow powder (12.0 mg, 0.0222 mmol).
