Reaction Steps

A mixture of 5 g of 5-methylthio-imidazo[2,1-b][1,3,5]benzothiadiazepine hydrochloride, 2.86 g of N-β-hydroxyethylpiperazine, and 175 ml of amyl alcohol is refluxed under nitrogen for 48 hrs. with stirring. The solvent is removed under vacuum, the residue is triturated with methylene chloride, washed with 2 N sodium hydroxide solution, dried over MgSO4, and evaporated to dryness. The residue is dissolved in 5 ml of methanol and treated with 2 N ethereal hydrochloric acid solutions to give 5-(4-β-hydroxyethylpiperazino)-imidazo[2,1-b][1,3,5]benzothiadiazepine dihydrochloride melting at 212°-214°.
