Reaction Steps

5-[(1RS,2RS)-1-Acetoxy-2-(3,4-dichlorophenyl)-4-(4-acetamido-4-phenylpiperidino)butyl]-1-phenylpyrazole. Using a procedure similar to that described in Example 7, except using 4-acetamido-4-phenylpiperidine as the amine component and 5-[(1RS,2RS)-1-acetoxy-2-(3,4-dichlorophenyl)-4-oxobutyl]-1-phenylpyrazole as the aldehyde component, the title compound was obtained as a white foam (65%; NMR: 7.58 (d,1), 7.48-7.21 (m,11), 7.09 (d, 1), 6.81 (dd, 1), 6.22 (d, 1), 6.09 (d, 1), 5.39 (s,1), 3.06 (m,1), 2.51 (m,2), 2.31 (m,2), 2.15-2.00 (m,7), 1.98 (s,3), 1.96 (s,3), 1.75 (m,1), 1.43 (m,1).
