Antiinflammatory Properties of 8-Aryl-5-isopropyl-2H-1,3-dioxoloquinazolin-6(5H)-ones and -thiones

A series of 8-aryl-5-isopropyl-2H-1,3-dioxoloquinazolin-6(5H)-ones and -thiones was prepared and evaluated for antiinflammatory activity.The 8-phenyl-, 8-(3-fluorophenyl)-, and 8-(4-fluorophenyl)-2H-1,3-dioxoloquinazolin-6(5H)-ones and the 8-phenyl-2H-1,3-dioxoloquinazolin-6(5H)-thione were found to exhibit activity in the range of indomethacin and proquazone.

Process for preparing 3,4-dihydro-2(1H)-quinazolinone derivatives

3,4-Dihydro-2(1H)-quinazolinones and quniazolinethiones such as 1-cyclopropylmethyl-4-phenyl-6-methoxy-3,4-dihydro-2(1H)-quinazolinone and its thione derivative, are prepared in high yield with high purity by heating the corresponding arylurea or thiourea

2-Amino-4,5-methylenedioxyphenyl nitriles

2-Amino-4,5-methylenedioxyphenyl nitriles are useful as intermediates for 2-amino-4,5-methylenedioxybenzophenonimines when reacted with a phenyl lithium or phenyl magnesium halide.
