Procedure

0.23 g (0.00073 mol) of 5-[4-(4-methoxy-phenyl)-piperazin-1-ylmethyl]-pyrimidine-2,4-diamine was dissolved in 250 ml of hot methanol. The solution was treated at room temperature with 0.84 ml (0.00293 mol) of 3.5N ethanolic hydrochloric acid. The solution was completely freed from the solvents and recrystallized from methanol/diethyl ether. 0.27 g (96%) of 5-[4-(4-methoxy-phenyl)-piperazin-1-ylmethyl]-pyrimidine-2,4-diamine hydrochloride (1:2.3) was obtained as white crystals; m.p. 215°-216°.
