Tetrahydro-2(1H)-quinazolinones and cyclohexene nitriles
-
, (2008/06/13)
A process for the production of 4-phenyl-2(1H)-quinazolinones and -4a,5,6,8a-tetrahydro-2(1H)-quinazolinones which comprises introducing the desired phenyl radical into a corresponding quinazolin-2,4(1H,3H)-dione by way of a Grignard reaction and hydrolysis of the resulting product.

-
, (2008/06/13)
Quinazoline-2(1H)-ones are prepared by dehydrogenating a 5,6,7,8-tetrahydro-2(1H)-quinazolinone with sulfur in the presence of a metal oxide, hydroxide or halide.
1-Isopropyl-7-methyl-4-(p-fluorophenyl)-2(1H)-quinazolinone
-
, (2008/06/13)
1-isopropyl-7-methyl-4-(p-fluorophenyl)-2(1H)-quinazolinone useful, for example, as a highly active anti-inflammatory agent of extended half line. The compound may be prepared by any of several processes, e.g. by reacting a 2-isopropylamino-4-methylbenzop
