Procedure
A mixture of 1.12 g of 5-hydroxy-2-(4-benzyloxyphenyl)pyrimidine, 1.30 g of 3-(R)-fluoroheptyl methanesulfonate, 1.2 g of potassium carbonate, and 50 ml of DMF was stirred at 80° C. for 4 hours. After cooling, the reaction mixture was diluted with water and extracted with ethyl acetate. The extract was washed with water and distilled to remove the solvent to obtain a residue weighing 2.12 g. Recrystallization of the residue from ethanol furnished 1.41 g (percent yield: 87.7%) of 5-[3-(R)-fluoroheptyloxy]-2-(4-benzyloxyphenyl)pyrimidine.
