실험 절차

Using the general procedure already described above, a solution containing 10.92 grams (40 moles) of 2-benzoyl-4-chlorophenylisothiocyanate in about 100 ml of ethyl ether was added dropwise to a stirred solution of 2.83 grams (44 moles) of ethanolamine in 200 ml of isopropanol. The reaction mixture was stirred overnight. The 6-chloro-3,4-dihydro-4-hydroxy-3-(2-hydroxyethyl)-4-phenyl-2(1H)-quinazolinethione precipitated as a white solid. The product was washed with a mixture of ethyl ether and isopropanol to give the final product which had a melting point of 238°-240° C. Final yield was 93%.
