반응 단계
To a suspension of ethyl 4-chloro-2-methylthio-5-pyrimidinecarboxylate (25 g) in ethanol (200 mL) was added 30% ammonium hydroxide (38 mL). After stirring 5 hours at room temperature, the reaction was concentrated in vacuo. The residue was suspended in water and filtered. The filter pad, washed with water then diethyl ether, gave 17.68 g of the title compound, CIMS (1% NH3 in CH4): 242=M+ +C2H5, 214=M+ +H (Base), 213=M+, 168=M+ -OEt.
