Compounds of the formula ##STR1## wherein: R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which may be the same or different, are selected from the group consisting of hydrogen, alkyl of 1-6 carbons, cycloalkyl of 3 to 6 carbons, alkenyl of 2-6 carbons, or together represent methylene groups --(CH.sub.2).sub.n --where n is a whole number from 1 to 6, provided that R.sub.1 and R.sub.2 or R.sub.3 and R.sub.4 are not both hydrogen; R.sub.5 and R.sub.6, which may be the same or different, are selected from the group consisting of hydrogen, halogen, nitro or --S(O).sub.n R.sub.7 where n is 0, 1 or 2 and R.sub.7 is an optionally substituted alkyl of 1-12 carbons atoms; and both Ar substituents are optionally substituted heteroaromatic rings or one Ar is such heteroaromatic ring and the other is optionally substituted phenyl, the optional substitution for Ar being halogen, nitro or --S(O).sub.n R.sub.7 where n and R.sub.7 have the value given above. The compounds are useful as inhibitors of human neutrophil elastase.
