Procedure

A suspension of 6-(3-fluoropyridin-4-yl)-3-methyl-2-(morpholin-4-yl)-3H-pyrimidin-4-one obtained in Example 6-1 (0.60 g, 2.07 mmol), and sodium methoxide (1.37 g, 25.4 mmol) in tetrahydrofuran (15 ml) was heated at 60° C. for 3 hours. The resulting suspension was partitioned between chloroform and brine and the aqueous layer was extracted with chloroform. The combined organic layer was washed with brine, dried over magnesium sulfate, and concentrated in vacuo. The residue was purified by silica gel chromatography eluting 5-10% methanol in chloroform to furnish 6-(3-methoxypyridin-4-yl)-3-methyl-2-(morpholin-4-yl)-3H-pyrimidin-4-one (0.40 g, 1.32 mmol, 64%) as white crystals.
