Abstract
A compound of the formula ##STR1## or a pharmaceutically acceptable salt thereof, wherein R.sup.1 is hydrogen; R.sup.2 is (C.sub.1 -C.sub.15) alkyl, (C.sub.3 -C.sub.15)alkenyl, phenyl, substituted phenyl, (C.sub.7 -C.sub.20)-phenylalkyl, or substituted (C.sub.7 -C.sub.20)phenylalkyl wherein the substituents on the substituted phenyl and substituted phenylalkyl are independently one or two of fluoro, chloro, (C.sub.1 -C.sub.3)alkyl, (C.sub.1 -C.sub.3 alkoxy, and trifluoromethyl; or R.sup.1 and R.sup.2 together with the nitrogen atom to which they are attached form a pyrrolodinyl, substituted pyrrolidinyl, piperidyl or substituted piperidyl group, wherein the substituents on said substituted pyrrolidinyl and piperidyl groups are independently one of (C.sub.1 -C.sub.6)alkyl, phenyl, and (C.sub.7 -C.sub.9)phenylalkyl; and R.sup.3 is hydrogen, (C.sub.1 -C.sub.6)alkyl, phenyl, substituted phenyl, (C.sub.7 -C.sub.9)phenylalkyl, or substituted (C.sub.7 -C.sub.9)phenylalkyl, wherein the substituents on the substituted phenyl and substituted phenylalkyl are independently one or two of fluoro, chloro, (C.sub.1 -C.sub.3)alkyl, (C.sub.1 -C.sub.3)alkoxy, and trifluoromethyl. The compounds are useful in treating inflammation or other leukotriene mediated diseases, including plumonary, asthmatic, allergic, and gastrointestinal diseases.
