Chloroform → 7-[1-(2-Hydroxyethyl)piperidin-4-ylmethoxy]-1,2,3,4-tetrahydroisoquinoline-2-carboxamidine dihydrochloride

Participants

Reaction Steps

To a solution of N,N′-di-tert-butoxycarbonyl-7-[1-(2-hydroxyethyl)-piperidin-4-ylmethoxy]-1,2,3,4-tetrahydroisoquinoline-2-carboxamidine (60 mg) in chloroform (0.6 ml)solution was added trifluoroacetic acid (0.3 ml), and the mixture was stirred at room temperature for 5 hours. After completion of the reaction, the solvent was evaporated and to the obtained residue was added a hydrogen chloride—ethanol solution and insoluble material was removed. The resultant mixture was concentrated and dried under reduced pressure to give the title compound (40 mg).
