Versuchsvorschrift
The solution of 22.2 g of 7,7-diphenyl-hexahydro-1,4-oxazepine and 0.2 g of hydroquinone in 50 ml of acrylonitrile is refluxed for 18 hours, cooled and evaporated. The residue is taken up in chloroform, the mixture filtered through a short column of silica gel, eluted with chloroform and the eluate evaporated. The residue is recrystallized from ethanol, to yield the 4-(2-cyanoethyl)-7,7-diphenyl-hexahydro-1,4-oxazepine melting at 106°-107°.
