Reaction Steps

A solution of 3,5-dimethyl-2-mercapto-4(3H)-quinazolinone (197 mg), 4-(4-toluoyl)benzyl bromide (336 mg) and 1N-sodium hydroxide/water (1 ml) in DMF (10 ml) was stirred at room temperature for 30 minutes. This reaction mixture was concentrated and the residue was dissolved in ethyl acetate, washed with water, dried, and concentrated. The residue was purified by silica gel column chromatography (hexane: ethyl acetate: chloroform=5:1:1) and crystallized from methanol to provide the title compound as colorless solid (140 mg).
