Procedure

4-Acetamidophenol (1.51 g.) and 39.4% aqueous formaldehyde (1.25 ml.) were dissolved in 50% aqueous ethanol, and 4-benzamidopiperidine (2.04 g.) was added. The resulting solution was heated under reflux for 30 minutes then left overnight at room temperature. The white solid was collected and purified by suspending in boiling ethanol and filtering to give the title compound (1.32 g.), m.p. 242° C. (Found: C, 68.15; H, 7.1; N, 11.3.C21H25N3O3 requires C, 68.6; H, 6.9; N, 11.4%).
