Procedure

To a solution of 2-pyridin-3-yl-benzaldehyde (1 g, 5.46 mmole) in methanol (10 ml) was added a solution of NaBH4 (0.26 g, 6.82 mmole) in methanol (10 ml) at 0° C. and stirred for 30 min at same temperature and then refluxed for 1 h. The unreacted NaBH4 was decomposed by solution of 6N HCl. The solvent was removed under reduced pressure and the residue was dissolved in 5N NaOH (20 ml) and extracted with ethyl acetate (3×20 ml). Combined organic extracts were dried (Na2SO4), filtered and concentrated to yield 0.95 g (94%) of product. MS (ESI+) m/z 186 (M+H)+.
