1-Polyhaloalkyl-2(1H)-quinazoline derivatives of the formula, ##STR1## wherein R is polyhaloalkyl having C.sub.2 -C.sub.4 alkyl; and R.sub.1, R.sub.2 and R.sub.3 are individually hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, nitro, trifluoromethyl or halogen, have excellent anti-inflammatory and analgesic activities with very low toxicity. These quinazolinone derivatives can be prepared, for example, by reacting a trihalogenoacetamidobenzophenone derivative with ammonia.
