Reaction Steps

2.4.6-Trichloropyrimidin (5.5 g, 30 mmol) was added at once to an ice cooled solution of sodium methoxide (3.3 g, 60 mmol) in methanol (120 ml). The mixture was stirred for one hour at about 5° C. and for two hours at room temperature. The solvent was removed under reduced pressure, water was added and the product was extracted three times with ethyl acetate. The combined organic phases were washed with water, dried with sodium sulphate and evaporated which gave the title compound (5.0 g, 95%), purity about 85%
