실험 절차

A solution of 3,5-dimethyl-2-mercapto-4(3H)quinazolinone (1.03 g), 4,4'-bis (bromomethyl)benzophenone (1.75 g), phenylpiperazine (810 mg), and 1N-sodium hydroxide/water (5.5 ml) in DMF (35 ml) was stirred at 60° C. for 1 hour. 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=4:1:1) and crystallized from isopropyl ether to provide the title compound as colorless solid (372 mg).
