Conditions

Temperature: 80 °C

Procedure

A mixture of 9.0 g of 5-methoxy-2-(4-hydroxyphenyl)pyrimidine, 8.45 g of benzyl chloride, 270 ml of dimethylformamide (DMF), and 12.3 g of potassium carbonate was stirred at 80° C. for 4 hours. The reaction mixture was diluted with water and extracted with ethyl acetate. The extract was washed with water and distilled to remove ethyl acetate to obtain 8.42 g (percent yield: 64.2%) of 5-methoxy-2-(4-benzyloxyphenyl)pyrimidine.
