Reaction Steps

3-(3,4-Dichlorophenyl)-3-(4-hydroxy-2-methyl-3-oxo-2,3-dihydro-1H-isoindol-1-yl)propionaldehyde (0.31 g) was coupled to 4-(2-oxoperhydropyrimidine-1-yl)piperidine (0.156 g) by a method similar to that described in Example 8. The reaction product was purified by chromatography and converted to the corresponding hydrochloride salt as described in the Example 8 to afford the title compound (0.378 g); mp 225°-240° C.; MS: m/z=531(M+1); NMR(CD3SOCD3): 1.60 (m,2), 1.65 (m,2), 2.98 (s,3), 4.37 (broad,1), 4.76 (d,1, J=3.5), 6.82 (m,2), 7.37 (m,4). Analysis for C27H32Cl2N4 O3.1.2 HCl.1.0 H2O: Calculated: C, 54.66; H#5.98, N, 9.44; Found: C, 54.70; H, 5.76; N, 9.15.
