実験手順

To a 0° C. solution of formic acid (0.09 mL) in dichloromethane (3 mL) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.23 g) and the mixture stirred for 15 minutes. To this mixture was added a solution of 4-(4-acetamido-4-phenylpiperidino)-2-(3,4-dichlorophenyl)-N-[3,5-bis(trifluoromethyl)benzyl]butyl amine (0.40) and N-methylmorpholine (0.13 mL) in dichloromethane (5 mL). The mixture was allowed to warm to room temperature overnight, and was diluted with 1N hydrochloric acid (5 mL), dichloromethane, and water (5 mL). The layers were separated and the the aqueous phase was extracted with dichloromethane (10 mL). The combined organic layers were washed (brine), dried, and evaporated to afford material which was purified by chromatography with dichloromethane:methanol (20:1) as eluent, to give a hydrate of the title compound (0.206 g); mp 108°-110° C.; NMR: 8.1-7.5 (m,6), 7.3 (m,6), 4.75-4.40 (m,2), 3.75-3.3 (m,4), 3.3-3.0 (m,4), 2.85 (m,1), 1.95 (s,3), 2.25-1.80 (m,4); MS: m/z=688(M+1,100%); TLC: Rf =0.46 (10:1 dichloromethane:methanol). Analysis for C33H33Cl2F6N3O2.1.50 H2O: Calculated: C, 55.39; H, 5.07; N, 5.87; Found: C, 55.38; H, 4.77; N, 5.84.
