A solution of 3-isopropoxyphenylacetic acid (670 mg) and 1,1'carbonyldiimidazole (590 mg) in tetrahydrofuran (15 mL) was stirred at reflux for 0.5 hours. The reaction was cooled to 23° C. and treated with a solution of N-[2-(3,4-dichlorophenyl)-2-(4-hydroxy-4-phenylpiperdino)ethyl]methylamine (940 mg) in tetrahydrofuran (40 mL). The reaction was stirred at 23° C. for 18 hours. The reaction was evaporated to a gold oil. The oil was partitioned between diethylether (100 mL) and 1 N hydrochloric acid (150 mL). The organic layer was treated with hydrochloric acid (g)/ether and evaporated to give a yellow oil which was dissolved in dichloromethane (10 mL) and added dropwise to diethylether (500 mL). The title compound precipitated as a white solid (480 mg); mp 127-132° C.; MS: m/z=555(M+1); NMR: 1.23 (d,3), 1.25 (d,3), 1.75 (m,2), 2.4 (m,1), 2.7 (m,1), 2.83 (s,3), 3.13 (m,2), 3.43 (m,2), 3.54 (s,2), 3.73 (m,1), 4.52 (m,1), 5.37 (m,1), 6.38 (d,1), 6.66 (s,1,), 6.73 (d,1), 7.01 (m,3,), 7.22 (m,2,), 7.46 (d,2), 7.7 (s,2,), 8.05 (s,1), 11.73 (s,1). Analysis Calculated: C, 61.95; H, 6.37; N, 4.66; Found: C, 61.94; H, 6.3; N, 4.56.
