Potassium Carbonate → HCID 178441858, compound

Participants

Reaction Steps

To a suspension of 2.0 g of impure 2-butyl-6-(bromomethyl)-4(1H)-quinazolinone in 35 ml of dimethylsulfoxide and 20 ml of water is added 1.0 g of potassium carbonate. The reaction mixture is heated at reflux for 6 hours, resulting in a complete solution. Upon cooling slowly to room temperature a white precipitate forms and is collected by filtration. The filter cake is purified by flash chromatography on silica gel, eluting with 9:1 chloroform-methanol to give 0.67 g of the desired product as a white solid. CI MASS SPEC 233(M+H).
