実験手順
0.17 g (0.00059 mol) of 5-(4-phenyl-piperazin-1-ylmethyl)-pyrimidine-2,4-diamine was dissolved in 120 ml of hot methanol. The solution was treated at room temperature with 0.32 ml (0.00118 mol) of 3.7N ethanolic hydrochloric acid. The solution was completely freed from the solvents and the residue was recrystallized from methanol/diethyl ether. 0.21 g (71%) of 5-(4-phenyl-piperazin-1-ylmethyl)-pyrimidine-2,4-diamine dihydrochloride was obtained as white crystals; m.p. 275°-277°.
