Reaction Steps

From 4-(5-methyl-3-ethyl-2-oxo-1-benzimidazolinyl)piperidine and 1,1-dioxido-2-(4-bromobutyl)-5-chloro-1,2-benzisothiazol-3(2H)-one (prepared as shown in Example 22) using the procedures described in Example 1 there was obtained a white solid upon formation of the HCl salt (from methanol), melting point 229-231° C. Analysis calculated for C26H31N4O4S.HCl.0.75 H2O: C, 53.82; H, 5.80; N, 9.66; found: C, 53.79; H, 5.52; N, 9.53. The NMR was consistent with the structure.
