실험 절차

To a solution of 2-mercapto-3-methyl-4(3H)-quinazolinone (1.0 g) and sodium hydroxide (250 mg) in 50% ethanol (15 ml)-DMF (15 ml) was added 3-(4-chloro-benzoyl)benzyl bromide (1.88 g) and the mixture was stirred at room temperature for 1 hour. This reaction mixtrue was poured in water and the resulting crystals were collected by filtration, rinsed with water and methanol, and recrystallized from methanol to provide the title compound as colorless solid (2.22 g). 1H-NMR (CDCl3) 8: 3.59(3H,s), 4.59(2H,s), 7.34-7.52(5H,m), 7.61-7.80(5H,m), 7.96(1H,d,J=2.0Hz), 8.22(1H,dd,J=8.0,1.4Hz).
