In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), to a ice-cold solution of 6-(2-methyl-[1,3]dioxolan-2-yl)-pyridine-2-carbaldehyde (713 mg, 3.69 mmol) in MeOH (10.0 mL) was added NaBH4 (180 mg, 4.57 mmol in four equal portions). The reaction mixture was then stirred for 1 h at rt. Water was added and the mixture was extracted with EA followed twice with EA-MeOH 9:1. The combined org. extracts were dried over Na2SO4, filtered, and the solvent was removed under reduced pressure to give the title compound as a pale yellow solid. LC-MS-conditions 02: tR=0.46 min; [M+H]+=196.49.
