実験手順

A 5.0 g. portion of 8-chloro-2-methoxy-11-(4-pyridyl)-dibenz[b,f][1,4]oxazepine (Example 1) is added to 2.5 g. of lithium aluminum hydride in 200 ml. of ether. The mixture is stirred and heated under reflux for 4 hours. Water is added dropwise to decompose the excess lithium aluminum hydride. The ether is decanted and the residue is extracted with methylene chloride which is then combined with the ether, dried and evaporated. The residue is crystallized from acetone-hexane giving 8-chloro-10,11-dihydro-2-methoxy-11-(4-pyridyl)-dibenz[b,f][1,4]oxazepine, mp. 186°-188° C.
