Sodium Hydroxide → 2-[4-(4-Acetoxybenzoyl)benzylthio]-3,5-dimethyl-4(3H)-quinazolinone

Participants

Reaction Steps

A solution of 3,5-dimethyl-2-mercapto-4(3H)-quinazolinone (917 mg), 4-(4-acetoxybenzoyl)benzyl bromide (1.785 g) and 1N-aqueous sodium hydroxide solution (4.5 ml) in methanol (20 ml) was stirred at room temperature for 4 hours. This reaction mixture was concentrated and extracted with chloroform and the extract was washed with water, dried, and concentrated. The residue was purified by silica gel column chromatography (hexane: ethyl acetate=6:1) to provide the title compound as colorless solid (4.26 mg).
