Procedure
To a solution of 6.9 g (0.30 mol) sodium in 185 ml isobutyl alcohol were added 43.4 g (0.30 mol) 2,4-diamino-6-chloropyrimidine. The mixture was heated under reflux with stirring for 10 h. The reaction mixture was then stirred at 80° C. for a further 36 h. After the reaction was ended the precipitated NaCl was separated off and the solution was concentrated to dryness. The residue was repeatedly taken up in ethanol and again concentrated in order to remove residual isobutyl alcohol. After drying, 6-(2-methylpropoxy)-2,4-diaminopyrimidine (41.3 g, 75%) was obtained as a yellow oil.
