To a flask charged with methyl (5-(3,5-difluorophenyl)furo[3,2-b]pyridin-3-yl)methylcarbamate (680 mg, 2137 μmol) was added MeOH (20 mL), then aqueous NaOH (18 mL, 6 N, 106 mmol). The solution was heated at reflux for 60 h. The solution was concentrated to remove MeOH, then partitioned between CH2Cl2 (30 mL) and NaHCO3 (10 mL). The layers were separated and the aqueous layer was extracted with CH2Cl2 (1×10 mL), then EtOAc (4×25 mL). The combined organic layers were concentrated to give a total of (5-(3,5-difluorophenyl)furo[3,2-b]pyridin-3-yl)methanamine (306.6 mg, 55% yield) as a brown foam. LRMS (ESI) m/z calcd for C14H11F2N2O (M+H) 261.1. found 261.2.
