Reaction Steps

174 mg (0.397 mmol) of 2-[4-(4-chlorophenyl)-2-oxo-2,3-dihydro-1H-imidazol-1-yl]-N-{1-methyl-1-[3-(trifluoromethyl)phenyl]ethyl}-acetamide from Example 234A, 12.8 mg (0.04 mmol) of tetra-n-butylammonium bromide and 37.5 mg (0.199 mmol) of potassium carbonate are placed in 0.45 ml of DMF and treated with 49.0 mg (0.437 mmol) of 1,1,1-trifluoro-2,3-epoxypropane. This is stirred for 1 hr at 130° C. The suspension is diluted with 5 ml of ethyl acetate and washed twice with 5 ml of water each time. The organic phase is dried over sodium sulphate and filtered. After evaporation the crude product is purified by preparative HPLC [Method 10]. 48 mg (22% of theory) of the target compound are obtained.
