実験手順

2-Morpholino-4,6-dichloropyrimidine (2.34 g; 10 mmol) and ethyl glycolate (1.3 g; 12 mmol) were dissolved in tetrahydrofuran (100 mL), and chilled in an ice bath. To the solution was added sodium hydride (300 mg; 12 mmol), and it was stirred overnight at ambient temperature. The solvents were evaporated, and the solid was dissolved in ethyl acetate (200 mL) which was then washed with water (2×100 mL). The organic layer was dried over magnesium sulfate, and evaporated to give (6-chloro-2-morpholin-4-yl-pyrimidin-4-yloxy)-acetic acid ethyl ester (3.16 g).
