Potassium Carbonate → Methyl 4-(3-tert.butylphenoxy)-6-dimethylamino-pyrimidin-5-yl-acetate

Participants

Reaction Steps

A mixture of methyl 4-chloro-6-dimethylamino-pyrimidin-5-yl-acetate (22.9 g, 100 mmol), 3-tert.butylphenol (15.0 g, 100 mmol), potassium carbonate (20.7 g, 150 mmol) and a catalytic amount of 18-crown-6 is heated in dimethylformamide (50 ml) at 130° C. for 6 hours. The reaction mixture is diluted with diethyl ether, washed with 2n NaOH and brine, dried (MgSO4) and evaporated to give methyl 4-(3-tert.butylphenoxy)-6-dimethylamino-pyrimidin-5-yl-acetate as a yellow oil (30 g).
