Reaction Conditions:

with sodium tetrahydroborate in methanol at 0; for 1 h;

Steps:

A
Sodium borohydride (2.2 g, 59.1 mmol) was added to a suspension of 5-bromo-pyridine-3- carbaldehyde (10. O g, 53.7 mmol) in MeOH (100 mL) at 0 °C. The mixture was stirred at 0 °C for 1 hour before it was quenched by the addition of water (5.0 mL). Evaporation of solvents afforded a light yellowish oil which was re-dissolved in EtOAc and washed with water. The organic layer was dried over anhy. Na₂S0₄, filtered and concentrated in vacuo to give the title compound (9.6 g, 95%) as colorless oil. MS: 188.0 & 190.0 (M+H⁺).
