    • A general synthetic procedure for the preparation of 2,4- diaminopyrimidines is outlined here. To a suspension of 2,4-dichloro-6- methylpyrimidine (2.01 g, 12.3 mmol) in distilled water (50 ml) was added 2,4,6-trimethylaniline (1.8 ml, 17.3 mmol) and the resulting mixture was heated at reflux for 72 hours. The cooled reaction mixture was extracted with DCM (4 x 30 ml, the combined organic layers dried (MgSO4) and concentrated in vacuo. The crude residue was subjected to gravity silica column chromatography and elution with 5% ethyl acetate:hexane gave 2-chloro-6-methyl-4-(2,4,6-trimethylanilino)pyrimidine 4 (1.14 g, 4.4 mmol, 35, as a white powder, mp. 208 °C.
