Reaction Steps

A solution of 2-(2,6-dibromo-phenoxy)acetamide (9.3 g, 0.03 mol) in tetrahydrofuran (100 mL) was heated to reflux and borane-dimethylsulfide (4.5 mL, 0.045 mL) was added in drops over a period of 15 min. After 3 h, 20 mL of ethanolic hydrogen chloride (2M, 0.4 mol) was added. The solution was refluxed for 30 min. Upon cooling to ambient temperature a white solid precipitated which was filtered and washed with diethyl ether (20 mL) to give 2-(2,6-dibromo-phenoxy)ethylamine, hydrochloride salt (7.25 g, 73.3%). MS: MH+=294. M.p. 249.7-252.3° C.
