Reaction Steps

A solution of 1-[2-(2-dimethylamino-ethoxy)-phenyl]-ethanone (4.35 g) in dimethylsulfoxide (8.8 ml) was added with 48% HBr (1.8 ml). The mixture was stirred at 80° C. for 6 hours under nitrogen stream. Then it was poured into methylene chloride (50 ml) and dried over magnesium sulfate. The mixture was neutralized to pH 7 with solid sodium bicarbonate, then filtered and evaporated under high vacuum at low temperature. The title compound was used without further purification.
