A compound of the formula:
- ##STR18## where R.sub.1 is hydrogen, alkyl of 1 to 7 carbon atoms, inclusive, haloalkyl of 1 to 7 carbon atoms, inclusive, phenyl, benzyl or cycloalkyl of 3 to 6 carbon atoms, inclusive, with the proviso that when R.sub.1 is benzyl or cycloalkyl, m = O;
- R.sub.2 and R.sub.5 are the same or different and are hydrogen, halogen, alkyl of 1 to 6 carbon atoms, inclusive, haloalkyl of 1 to 6 carbon atoms, inclusive, or phenyl;
- R.sub.1 and R.sub.2 together with the attached carbon atom can be cycloalkyl of 3 to 6 carbon atoms, inclusive, when m = O;
- m is O or 1 provided that when m = O, R.sub.1 is not hydrogen and when m = l at least one of R.sub.2 or R.sub.5 is hydrogen;
- R.sub.3 is hydrogen, alkyl of from 1 to 8 carbon atoms, inclusive, phenyl or benzyl;
- R.sub.4 is hydrogen, or alkyl of from 1 to 6 carbon atoms, inclusive, and R.sub.3 and R.sub.4 can be joined together to form a heterocyclic ring selected from the group consisting of pyrrolidine and piperidine;
- A and B are the same or different and are hydrogen, alkyl of from 1 to 6 carbon atoms, inclusive, phenyl, halogen, cyano, haloalkyl of 1 to 6 carbon atoms, inclusive, alkoxy or alkylthio in which the alkyl group is from 1 to 3 carbon atoms, inclusive or trifluoromethyl and when adjacent can be joined to form a ring of from 5 to 7 carbon atoms, inclusive;
- X is halogen, nitro, cyano, acetyl, dimethylcarbamoyl, alkyl, haloalkyl, alkoxy or carboalkoxy in which the alkyl group is from 1 to 3 carbon atoms, inclusive, phenyl, benzyl, 2-phenylethyl and n is 0, 1, or 2;
- or an acid addition salt thereof.
