Reaction Steps

3-(3,4-Dichlorophenyl)-3-(2-ethyl-3-oxo-2,3-dihydro-1H-isoindol-1-yl) propionaldehyde (0.724 g) was coupled to 4-(2-methylsufonyl-phenyl)piperidine (0.706 g) by a method similar to that described in Example 8. The reaction product was not purified by chromatography but converted to the hydrochloride salt to afford the title compound (0.64 g); mp 168-175° C. (d); MS: m/z=585(M+1); NMR (CDCl3): 1.19 (m,3), 2.0 (m,3), 2.35 (m,7), 2.95 (s,3), 4.87 (m,1), 6.56-8.01 (m,11). Analysis for C31H34Cl2N2O3S.1.5 HCl.1.5 H2O: Calculated: C, 55.79; H, 5.82, N, 4.20; Found: C, 55.90; H, 5.45; N, 4.20.
