Sodium borohydride → HCID 86695915, compound

Participants

Reaction Steps

To a stirred solution of 2-amino-4-(4-chloro-2-fluorophenyl)nicotinaldehyde (50 mg, 0.199 mmol) in MeOH (2 mL) and THF (5 mL) was added sodium borohydride (9.06 mg, 0.239 mmol) then the solution was stirred for 1 h. The volatile organics were removed under reduced pressure and the residue was quenched by addition of saturated aqueous ammonium chloride solution (10 mL). The reaction mixture was extracted with CH2Cl2 (2×10 mL). The combined organic extracts were washed with brine (1×10 mL), dried over sodium sulfate and concentrated under reduced pressure to yield (2-amino-4-(4-chloro-2-fluorophenyl)pyridin-3-yl)methanol (50 mg, 0.198 mmol, 21% yield for two steps). LCMS (ESI) m/e 253 [(M+H)+, calcd for C12H11ClFN2O 253.0]; LC/MS retention time (Method C): tR=1.48 min.
