Participants

Reaction Steps

A mixture of morpholine (697 ml.), cyclohexanone (820 ml.) and hexane (800 ml.) is heated to reflux under nitrogen with a Dean-Stark trap for 18 hours. The aqueous phase (206 ml.) is collected in the distillate trap. The mixture is distilled under vacuum increasing the vacuum to 29 inches and 90°-100° to give the title compound as an oily residue.
