Compounds of the formula ##STR1## wherein R is hydrogen, ##STR2## R.sub.1 and R.sub.2 are independently selected from hydrogen, lower alkyl, and cycloalkyl or R.sub.1 and R.sub.2 taken together with the nitrogen atom to which they are attached form a ring of the formula ##STR3## N IS 0 OR AN INTEGER FROM 1 TO 3; M IS AN INTEGER FROM 1 TO 3; R.sub.3 and R.sub.4 are independently selected from hydrogen and lower alkyl; X is hydrogen, halogen, lower alkyl, lower alkoxy, or nitro; and their salts; are disclosed. These compounds possess useful antiinflammatory properties.
