Participants

Reaction Steps

400 mg (1.96 mmol) of 3-propyl-2,3,4,5-tetrahydro-1H-3-benzazepine-7-amine and 1.86 mmol of 4-acetylaminobenzenesulfonyl chloride were dissolved in 20 ml of tetrahydrofuran at room temperature, 0.82 ml (5.87 mmol) of triethylamine was added dropwise, and the mixture was stirred at room temperature overnight. After the solvent had been evaporated off, 20 ml of water were added, and the mixture was acidified with 1 mol of hydrochloric acid and extracted with 50 ml of diethyl ether. The aqueous phase was made basic at pH 9-10 with 1 mol of sodium hydroxide solution and then extracted with diethyl ether. The residue obtained after drying with sodium sulfate and after removal of the solvent was converted into the hydrochloride with ethereal hydrochloric acid. Yield: 280 mg (35% of theory)
