Reaction Steps
A mixture of 1-(4-hydroxybutyl)-2,4(1H,3H)-quinazolinedione 290 mg), thionyl chloride (0.54 ml), and pyridine (98 mg) in tetrahydrofuran (10 ml) was refluxed for 2 hours. After evaporation of the solvents, the residue was dissolved in chloroform, washed in turn with water, saturated sodium bicarbonate and brine, dried over magnesium sulfate, and evaporated. Crude material was crystallized from ethyl ether-isopropyl ether to give 1-(4-chlorobutyl)-2,4(1H,3H)-quinazolinedione (226 mg) as a powder.
