실험 절차

40 g 1-(1-carbobenzoxyaminoethyl)-3,4-dihydro-6,7-dimethoxyisoquinoline are dissolved in 450 ml 40% HBr/acetic acid. The mixture is maintained at room temperature for 1 hour and then concentrated in a vacuum to give a crystalline residue of 1-(1-aminoethyl)-3,4-dihydro-6,7-dimethoxyisoquinoline dihydrobromide which is washed with ether before further use (M.Pt. 234°-235°).
