2-[4-Dimethylamino-4-(3-fluorophenyl)cyclohexylidene]-N-(3-phenylpropyl)acetamide (150 mg, 0.35 mmol) was dissolved in ethyl methyl ketone (10 ml) with gentle heating and trimethylchlorosilane (0.082 ml, 0.65 mmol) was added. After stirring at RT for 2 h, the reaction mixture was concentrated to dryness. The residue was stirred briefly with ether (10 ml) and the hydrochloride was isolated as a colourless solid with an m.p. of 230-233° C. in a yield of 98% (184 mg).
