Reaction Steps
A suspension of iron powder (40.8 g, 0.730 mol), ammonium chloride (64.7 g, 1.21 mol) and 2-bromoanisole (50 g, 0.215 mol) in water (1.5 L) and MeOH (1 L) was stirred overnight at 75° C. The solid was filtered off and the liquid was diluted with ethyl acetate, washed with brine, dried over sodium sulfate, filtered and the solvents were evaporated under vacuum. 43.1 g of the title compound were obtained. Brown solid, ISP-MS: m/e=203.1 ([M+H]+).
