Procedure

4.0 G. of 5'-[(2,4-diamino-5-pyrimidinyl)methyl]-3'-dimethylamino-2'-methoxy-N-methylacetanilide (prepared as described in the first paragraph of Example 2) and 100 ml. of 1-N hydrochloric acid were boiled under reflux for 2 hours. After neutralization and evaporation in vacuo, purification of the residue over silica gel with methylene chloride/propanol (8:2) and recrystallization from ethanol, there was obtained 2,4-diamino-5-[3-dimethylamino-4-methoxy-5-(methylamino)benzyl]pyrimidine, having a melting point of 183° C.
