84 mg of sodium hydride are added to a solution of 700 mg of ethyl [4-({[(2-methylpropan-2-yl)oxy]carbonyl}oxy)-6-(morpholin-4-yl)pyrimidin-2-yl]acetate in 8 ml of N,N-dimethylformamide under argon. The reaction mixture is then stirred for 15 minutes at 0° C. 0.130 ml of methane iodide is then added and the resulting mixture is stirred at ambient temperature overnight. 0.5 ml of water is added and the reaction mixture is concentrated to dryness under reduced pressure. After purification by silica column chromatography, elution being carried out with a gradient of heptane/ethyl acetate eluent of 0% to 50% and then with ethyl acetate at 100%. 150 mg of ethyl 2-[4-({[(2-methylpropan-2-yl)oxy]carbonyl}oxy)-6-(morpholin-4-yl)pyrimidin-2-yl]propanoate are obtained in the form of a colourless oil.
