Reaction Steps

Borane in tetrahydrofuran (1.0M, 26.3 ml) was added dropwise to a tetrahydrofuran solution of 2-(3-bromophenyl)-N-methyl-acetamide (1.5 g, Example 12a)) at 0° C. Once addition was complete the solution was refluxed at 90° C. for 20 hours. The solution was cooled to room temperature, acidified with 6M hydrochloric acid (10 ml) and refluxed for a further hour. The solution was cooled to room temperature and extracted with diethyl ether. The aqueous layer was basified with 10% sodium hydroxide and extracted with ethyl acetate. The extracts were dried over anhydrous magnesium sulfate, filtered and concentrated. The residue was converted to the hydrochloride salt by treatment with a 4M solution of hydrochloric acid in dioxan to give the sub-title compound as a solid (0.727 g).
