実験手順

Step-2: To a stirred solution of 100 mL (400 mmol) of 4N HCl in dioxanes was added the step-1 product, 4-(4-cyanophenoxy)piperidine-1-carboxylic acid tert-butyl ester, (12.60 g, 0.0417 mol) and the mixture stirred 2 h, and 150 mL of 67% Et2O/hexanes added. The resulting slurry was filtered and dried under vacuum (1 torr, 60° C.) to afford the step-2 product, 4-(piperidin-4-yloxy)benzonitrile hydrochloride, as a white solid (9.10 g, 91%): LCMS [MH+]203, Rt 1.23.
