Reaction Steps

A sealed vial was charged with 1-(2-methoxyethyl)-7-(4-nitrophenylthio)-1H-pyrrolo[3,2-b]pyridine (0.147 g, 0.446 mmol) and methanol (5 mL). Tin (II) chloride dihydrate (0.504 g, 2.23 mmol) was added and the reaction was stirred at 50° C. for 3 hours. The reaction was concentrated and dissolved in DCM. The solution was washed with saturated sodium bicarbonate solution, which was extracted with DCM. The combined organic layers were washed with water, dried with sodium sulfate, filtered, and concentrated. The material was purified via column chromatography (gradient elution 0-10% DCM:MeOH) to afford 4-(1-(2-methoxyethyl)-1H-pyrrolo[3,2-b]pyridin-7-ylthio)benzenamine as an orange oil that solidified under high vacuum. MS: M+H+=300.1.
