Reaktionsschritte
A mixture of 5.8 g (0.027 mole) 4-hydroxy-6-methyl-2-trichloromethylpyrimidine, 3.3 g (0.024 mole) potassium carbonate, 3.2 g (0.024 mole) pyrrolidinecarbonyl chloride, and 100 ml acetone was refluxed 5.3 hours. A precipitate was filtered out and the filtrate rotary evaporated to give 9.8 g residue. This was taken up in chloroform, the solution washed with 1% sodium hydroxide, water, and dried over anhydrous magnesium sulfate. Rotary evaporation yielded 4.4 g residue which was recrystallized from petroleum ether to give 2.2 g (28% yield; mp 93°-95° C.) of product. The structure was confirmed via infrared and elemental analysis.
