Procedure
The intermediate methyl 2-[2,4-dimethyl-6-(1-(2-methylphenyl)-1H-pyrazol-4-yloxy)-pyrimidin-5-yl]-acetate (6.0 g, 17 mmol), sodium hydride (0.9 g, 37 mmol) and N,N-diformylmethylamine (6 ml) in a mixture of dimethylformamide (20 ml) and 1,2-dimethoxyethane (20 ml) is stirred at 45° C. for 3 hours. Methyliodide (4.2 g, 30 mmol) is added at room temperature and stirring is continued for additional 16 hours. Dilution with ether, washing with brine, drying and chromatography on silicagel (eluant ethyl acetate/hexane 3:7) gives methyl 2-[2,4-dimethyl-6-(1-(2-methylphenyl)-1H-pyrazole-4-yloxy)-pyrimidin-5-yl]-3-methoxyacrylate as a colorless oil.
