Reaction Steps

To a solution of 3-bromobenzaldehyde (18.5 g, 100 mmol) in MeOH (100 mL) was added MeNO2 (12.2 g, 200 mmol) at 0° C. followed by addition of KOH (11.2 g, 200 mmol). After 2 hours, MeOH was removed in vacuo and the resulting mixture was partitioned between ethyl acetate and water. Ethyl acetate extracts were dried over MgSO4 and concentrated to give 20 g crude mixture. This crude mixture was dissolved in AcOH (200 mL), to which CrO3 (12.0 g, 120 mmol) was added. Acetic acid was removed under vacuo after 2 hours and water (200 mL) was added and extracted with ethyl acetate (3×100 mL). The combined organic extracts were dried over MgSO4, filtered and then concentrated under vacuo. dichloromethane (20 mL) was added and the titled compound (8.5 g, 35% for 2 steps) was precipitated out and collected by filtration.
