Procedure

3.7 g of 2-azido-1,2,3,4-tetrahydro-tribenzo(b,d,f)-oxepine are added to a suspension of 3 g of lithiumaluminiumhydride in 100 ml of dry ether. The mixture is refluxed for one hour. After the mixture has been cooled down, 12 ml of water are added carefully after which the mixture is stirred for some time. The suspension is filtered and after that the filtrate is dried and evaporated to dryness. The residue is converted with maleic acid into the maleate. Melting point of the maleate: 198°-202° C. Yield 85%.
