3.00 g (11.75 mmol) of methyl 1-amino-4-methoxy-4-(trifluoromethyl)cyclohexanecarboxylate (Example 22A) and 1.19 g (11.75 mmol) of triethylamine were dissolved in 40 ml of dichloromethane. 2.65 g (10.69 mmol) of (5-bromo-2-methylphenyl)acetyl chloride (Example 3A), dissolved in 40 ml of dichloromethane, were added dropwise to this solution, and the reaction mixture was stirred at room temperature overnight. For work-up, the mixture was diluted with dichloromethane and the organic phase was washed with aqueous saturated sodium bicarbonate solution and with aqueous 1% strength citric acid. After drying over sodium sulphate, the organic phase was concentrated and the product was dried. This gave 4.79 g (87% of theory) of the title compound as a beige powder.
