실험 절차

A solution of 3,4-dichloroaniline, cycloheptene oxide, and concentrated HCl (2 ml.) is heated at reflux temperature for seven (7) days. The unreacted epoxide is evaporated and the residue is treated with excess ethereal HCl, and a syrup results. This is washed with ether. The residue is crystallized and recrystallized from methanol/ether (1/5.5, v/v) to give trans-3,4-dichloro-N-(2-hydroxycycloheptyl)aniline, hydrochloride salt.
