実験手順

To a solution of 4-(((6-(2,4-dichlorophenyl)-5-(ethoxycarbonyl)-2-(thiazol-2-yl)-3,6-dihydropyrimidin-4-yl)methyl)morpholine-3-carboxylic acid (0.12 g, 0.23 mmol) and TEA (0.06 g, 0.6 mmol) in DMF (6 mL) was added chloromethyl pivalate (0.12 g, 0.8 mmol). And the mixture was stirred at 60° C. for 3 hours, and cooled to 25° C. To the reaction mixture was added DCM (100 mL). The organic layer was washed with brine (80 mL×6) and dried over unhydrous Na2SO4. The crude product was purified by a silica gel column chromatography (PETROLEUM ETHER/EtOAc (V/V)=8/1) to give the title compound as yellow oil (0.09 g, 62%). The compound was characterized by the following spectroscopic data:
