실험 절차

1-[4-(4-Tert-butyl-phenyl)-piperazin-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-(4-Tert-butyl-phenyl)-piperazine was prepared with a 92% yield from 1-(4-Tert-butyl-phenyl)-piperazine and chloroacetyl chloride using the procedure illustrated in Example 4. In the second step, the 1-[4-(4-tert-butyl-phenyl)-piperazin-1-yl]-2-[trans-4-(4-nitro-3-trifluoromethyl-phenylamino)-cyclohexyloxy]-ethanone was prepared from the 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 (32% yield). The structure was confirmed using Protocol II-A. Calculated mass=563; observed mass=563; HPLC retention time=4.79 min.
