To a solution of 4-(4-chloro-2-fluorophenyl)-2-methylnicotinaldehyde (60 mg, 0.240 mmol) in MeOH (2 mL) at 0° C., was added NaBH4 (27.3 mg, 0.721 mmol) and the solution stirred for 3 h at RT. The mixture was concentrated and diluted with EtOAc (15 mL) and water (10 mL). The organic layers were dried over Na2SO4, filtered and concentrated under reduced pressure to afford (4-(4-chloro-2-fluorophenyl)-2-methylpyridin-3-yl)methanol (0.15 g, 0.596 mmol, 89% yield) as a brown solid. LCMS (ESI) m/e 252.03 [(M+H)+, calcd for C13H12ClFNO 252.1]; LC/MS retention time (Method G): tR=0.80 min.
