Procedure

10.2 g of 4-benzyl-2,3,4,5-tetrahydro-benzo[f][1,4]oxazepine were dissolved in 100 mL of ethanol and hydrogenated for 5 hours at room temperature using 1.2 g of palladium (10% on carbon) as catalyst. Filtration followed by removal of the solvent in vacuo gave 6.1 g of 2,3,4,5-tetrahydro-benzo[f][1,4]oxazepine as an oil. EI-MS: 149 (M+).
