Reaction Steps
A solution of 12.3 g (0.05 mole) of 5-chloro-2-methylaminobenzophenone and 6 ml (0.1 mole) of methyl isocyanate in 50 ml of methylene chloride was refluxed for 3 days, and then cooled. The solid portion of the reaction mixture was collected on a filter and washed with methylene chloride to give 7.05 g (47%) of 6-chloro-3,4-dihydro-4-hydroxy-1,3-dimethyl-4-phenyl-2(1H)-quinazolinone as light yellow crystals; mp 174°-176°; 1H nmr (DMSO-d6) δ 2.67 ppm (s, 3H), 3.38 ppm (s, 3H), 6.8-7.7 ppm (m, 9H).
