Procedure
An ethanol solution of 6-[2-(1-pyrrolidinyl)ethylamino]-7,8,9,10-tetrahydro-1,2,4-triazolo[3,4-a]phthalazine was treated with an excess of ethereal hydrogen chloride. The precipitate which formed was separated by filtration to give 6-[2-(1-pyrrolidinyl)ethylamino]-7,8,9,10-tetrahydro-1,2,4-triazolo[3,4-a]phthalazine dihydrochloride melting at about 274°-275° C.
