Versuchsvorschrift

Into a Parr pressure reactor was placed 9-nitro-2,5-dihydro-benzo[b]oxepine (200 mg, 0.001 mol) in methanol (10 mL, 0.3 mol). To this solution was added palladium on carbon 10% (10 mg). The reaction was placed under 50 psi hydrogen and shaken overnight. Reaction mixture was filtered through celite, rinsed with methanol (3×10 mL) and concentrated in vacuo to give 2,3,4,5-tetrahydro-benzo[b]oxepin-9-ylamine as an off-white solid (142 mg, 83%).
