Versuchsvorschrift

Here, 1-[7,8-dimethoxy-1,3,4,5-tetrahydro-2H-3-benzazepin-2-on-3-yl]-3-[N-benzyl-N-(6,7-dimethoxy-1,2,3,4-tetrahydronaphth-2-yl)-amino]-propane (0.78 g, 0.0014 mol) is hydrogenated in glacial acetic acid (20 ml) in the presence of 10% palladium/charcoal (0.1 g) for 3 hours at ambient temperature under pressure (5 bar). The catalyst is removed by suction filtering, the glacial acetic acid is distilled off in vacuo, the residue is taken up in methylene chloride/saturated potassium carbonate solution, the organic phase is washed with water, dried over magnesium sulphate, evaporated again and purified over alumina (100 g), neutral, activity II, with methylene chloride and then with increasing amounts of ethanol (up to 40%). The hydrochloride is precipitated from a solution in acetone with ethereal hydrochloric acid. Yield: 0.45 g Mp: 222°-223° C.
