Procedure
1-[4-(2,4-Difluoro-phenyl)-piperidin-1-yl]-2-[trans-4-(4-nitro-3-trifluoromethyl-phenylamino)-cyclohexyloxy]-ethanone was prepared using a two-step synthesis. In the first step, 1-chloracetyl-4-(2,4-difluoro-phenyl)-piperidine (also known as 2-chloro-1-[4-(2,4-difluoro-phenyl)-piperidin-1-yl]-ethanone) was prepared from 4-(2,4-difluoro-phenyl)-piperidine and chloroacetyl chloride using the procedure illustrated in Example 4. In the second step, the 1-[4-(2,4-difluoro-phenyl)-piperidin-1-yl]-2-[trans-4-(4-nitro-3-trifluoromethyl-phenylamino)-cyclohexyloxy]-ethanone was prepared from the 1-chloracetyl-4-(2,4-difluoro-phenyl)-piperidine and trans-4-(4-nitro-3-trifluoromethyl-phenylamino)-cyclohexanol (prepared in accordance with Example 5) using the procedure illustrated in Example 11. This afforded the product as a yellow solid (16% yield). The structure was confirmed using Protocol II-A. Calculated mass=542; observed mass=543; HPLC retention time=4.36 min.
