Versuchsvorschrift

13.8 kg of 4-(4-fluorophenyl)-6-hydroxy-2-methylpyrimidine and 11.5 kg of phosphorus oxychloride were refluxed in acetonitrile, and stirred for 4 hours. The reaction solution was combined with water, and the precipitated crystal was separated, and the resultant crystal was washed and dried to obtain 14.6 kg of the target compound as a pale yellow crystal.
