Procedure

A mixture of 4-amino-6-methyl-5-{[4-(trifluoromethyl)phenyl]ethynyl}pyrimidine (2 g), triethylamine (0.76 g), ethyl 5-chloromethyl-2-furancarboxylate (1.4 g) and toluene (60 ml) was heated to reflux while stirring for 10 hours. The mixture thus obtained was concentrated under reduced pressure. After the resultant residue was washed with water added thereto, an organic phase was dried over anhydrous sodium sulfate and evaporated. The resultant residue was purified by column chromatography to obtain a target substance (0.6 g). The target substance was subjected to e.g., proton nuclear magnetic resonance spectrometry (1H-NMR) and mass spectrometry (MS) and confirmed as the titled compound. Furthermore, MS measurement result is shown.
