Participants

Reaction Steps

In a reaction flask were charged 3.5 g of 5-[3-(S)-fluoroheptyloxy]-2-(4-hydroxyphenyl)pyrimidine synthesized in the same manner as in steps 1 to 7 of Example 1, 3.17 g of potassium carbonate, 70 ml of DMF, and 6.4 g of 2-(S)-tetrahydropyranyloxyheptyl tosylate in a nitrogen stream, and the mixture was allowed to react at 80° C. for one day. After cooling, water was added thereto, the reaction mixture was extracted with toluene, and the solvent was removed from the extract to obtain 7.6 g of a crude product. Purification by silica gel column chromatography gave 6.4 g of the titled compound.
