Reaction Steps

A mixture of ethyl 6-(bromomethyl)-4-(2-nitrophenyl)-2-(thiazol-2-yl)-1,4-dihydropyrimidine-5-carboxylate (2.4 g, 5.3 mmol), morpholine-3-carboxylic acid hydrochloride (0.9 g, 5.37 mmol) and potassium carbonate (1.48 g, 10.74 mmol) in ethanol (60 mL) was stirred at 25° C. for 12 hours. The 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 light yellow solid (1.1 g, 41%). The compound was characterized by the following spectroscopic data:
