Reaction Steps
Sodium borohydride (0.75 g) was added portionwise to a stirred suspension of 3,5-dibromobenzaldehyde (10.46 g) in methanol (50 ml) at 0° C. The mixture was stirred at 0° C. for 30 minutes, allowed to warm to room temperature and then its pH was adjusted to 2 using concentrated hydrochloric acid. Evaporation under vacuum provided a residue which was partitioned between ethyl acetate and water. The organic phase was washed with water, dried(MgSO4), then evaporated under vacuum to furnish the title compound as a solid (10.0 g), m.p. 103°-104° C. Found: C, 31.98; H, 2.23. C7H6Br2O requires C, 31.61; H, 2.77%.
