Participants

Reaction Steps

p-Nitrophenylethyl bromide (1.15 g.) was refluxed for 20 hours in isopropyl alcohol (75 ml.) with 4-benzamidopiperidine (1.032 g.) and anhydrous potassium carbonate (1.037 g.). The mixture was filtered hot, refrigerated and product was filtered off (547 mg.), washed with cold isopropyl alcohol and ether. The filtrate was evaporated to yield more product (1.4 g.). Recrystallisation from a mixture of benzene and petroleum ether (b.p. 40°-60° C.) gave the title compound, m.p. 209°-216° C. (Found: C, 68.2; H, 6.7; N, 11.8. C20H23N3O3 requires C, 68.0; H, 6.6; N, 11.9%).
