Claim 1
Independent Claim
261 words
A compound of the formula ##STR61## wherein m is one or two; R 3 is hydrogen, alkyl, substituted alkyl, aryl-(CH 2 ) p -, or substituted aryl-(CH 2 ) p -; p is zero or an integer from 1 to 6; ##STR62## represents an aromatic heteroatom containing ring selected from the group consisting of ##STR63## X 1 is S or NH; X 2 is S, O, or NH; and R 13 is hydrogen, lower alkyl, lower alkoxy, lower alkylthio, chloro, bromo, fluoro, trifluoro-methyl, amino, --NH(lower alkyl), --N(lower alkyl) 2 , or hydroxy; the term "alkyl" refers to straight or branched chain radicals of one to seven carbon atoms; the term "substituted alkyl" refers to such straight or branched chain radicals of 1 to 7 carbons wherein one or more hydrogens have been replaced by a hydroxy, amino, halo, trifluoromethyl, cyano, --NH(lower alkyl), --N(lower alkyl) 2 , lower alkoxy, lower alkylthio, or carboxy; the term "aryl" refers to phenyl, 1-naphthyl, and 2-naphthyl; the term "substituted aryl" refers to phenyl, 1-naphthyl, and 2-naphthyl having a substituent selected from lower alkyl, lower alkoxy, lower alkylthio, halo, hydroxy, trifluoromethyl, amino, --NH(lower alkyl), and --N(lower alkyl) 2 , and di- and tri-substituted phenyl, 1-naphthyl, and 2-naphthyl wherein said substituents are selected from methyl, methoxy, methylthio, halo, hydroxy, and amino; the term "lower alkyl" refers to straight or branched radicals of 1 to 4 carbons; the terms "lower alkoxy" and "lower alkylthio" refer to such lower alkyl groups as defined above attached to an oxygen sulfur; and the term "halo" refers to chloro, bromo, fluoro, and iodo.
