Procedure

A solution of 55 parts of the ether obtained in the preceding paragraph in 800 parts of ethanol was hydrogenated over Raney nickel catalyst at room temperature and atmospheric pressure. When hydrogen uptake ceased, the catalyst was removed by filtration and the ethanol solvent was evaporated. The residue was then dissolved in 500 parts by volume of hexane, filtered, and then cooled. There was then obtained yellowish-white crystals which were separated by filtration to give 8-(trifluoromethyl)10,11,-dihydrodibenz-[b,f][1,4]oxazepine melting at about 86°-88° C.
