Versuchsvorschrift

Tetrahydro-1-(5-trifluoromethyl-1,3,4-thiadiazol- 2-yl)-3-(1,1-dimethylprop-2-ynyl)-6-hydroxy-2(1H)-pyrimidinone (0.05 mole), triethylamine (0.06 mole) and benzene (50 ml) are charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and reflux condenser. 2-Methylbenzoyl chloride (0.05 mole) is then added dropwise with stirring. After the addition is completed, the reaction mixture is heated at reflux with continued stirring for a period of about 30 minutes. After this time the reaction mixture is filtered and the filtrate is stripped of solvent under reduced pressure to yield a solid residue. The residue is recrystallized to yield the desired product tetrahydro-1 -(5-trifluoromethyl-1,3,4-thiadiazol-2-yl)-3-(1,1-dimethylprop- 2-ynyl)-6-(2-methylbenzoyloxy)-2(1H)-pyrimidinone.
