The less polar diastereoisomer of 2-[4-dimethylamino-4-(3-fluorophenyl)cyclohexyl]-N-[2-(1H-indol-3-yl)ethyl]acetamide (86 mg, 0.204 mmol) was dissolved in ethyl methyl ketone (5 ml), and chlorotrimethylsilane (0.038 ml, 0.3 mmol) was added. After 1 h ether (30 ml) was added to the reaction mixture and the mixture was stirred at RT for 30 min. The hydrochloride was isolated as a colourless solid in a yield of 94% (87 mg) with an m.p. of 135-140° C. (Example 50).
