実験手順

A mixture of ethyl 4-(2-bromo-4-fluorophenyl)-6-(bromomethyl)-2-(thiazol-2-yl)-1,4-dihydropyrimidine-5-carboxylate (7.7 g, 15.3 mmol), (S)-2,2-dimethylmorpholine-3-carboxylic acid (2.44 g, 15.3 mmol) and potassium carbonate (4.23 g, 30.6 mmol) in anhydrous ethanol (154 mL) was stirred at 25° C. for 16 hours. The reaction mixture was filtered and the filtrate was concentrated in vacuo. The residue was purified by a silica gel column chromatography (DCM/MeOH (V/V)=25/1) to give the title compound as a yellow solid (5.8 g, 65%). The compound was characterized by the following spectroscopic data:
