International Classification:

C07D33322
C07D30736

US Classification:

549 77

Abstract:

A process for preparing a compound of the structure I ##STR1## where A is oxygen and sulfur and R. sup. 1 is selected from the group consisting of hydrogen, halogen, alkyl of one to six carbon atoms, alkoxy of one to six carbon atoms, and trifluoromethyl, and R. sup. 2 is alkyl of one to four carbon atoms, comprising coupling a compound of formula II: ##STR2## where X is bromine or iodine, with an N-hydroxyurea compound of formula III: ##STR3## in the presence of a palladium catalyst followed by reaction of the product thus formed with an alkali metal isocyante. The compounds of formula I are inhibitors of the enzyme 5-lipoxygenase and are thus useful as therapeutic agents for the treatment of allergic and inflammatory disease conditions.
