実験手順
A stirred mixture of 7.02 g (0.02 mole) of 1-(2-benzoyl-4-chlorophenyl)-3-phenylurea and 4.17 g (0.06 mole) of hydroxylamine hydrochloride in 100 ml of ethanol was refluxed for 22 hr, and then cooled. The suspended solid was collected on a filter, washed with ethanol, and dried in air to give 3.82 (70%) of 6-chloro-4-phenyl-2(1H)-quinazolinone as yellow crystals; mp 267°-269°.
