Ar is an aryl ring or a 5 or 6 membered heteroaryl ring, either of the aryl ring or the heteroaryl ring being optionally substituted with one or more substituents selected from the group consisting of halogen, cyano, —OH, —OR1, —NH2, —NHR1, —NR1R2, —CONH2, —CONHR1, —CONR1R2, —SO2NH2, —SO2NHR1, —SO2NR1R2, —NHCOR1, —NHCO2R1, —NHCONHR1, —NHSO2NHR1, —NHSO2R1, —COR1, —CO2R1, —CH2NHR1, —CH2NR1R2, —OCH2CO2R1, —OCH2CONHR1, —OCH2CONHR1R2, —OCH2COR1, —OCH2CONHR1, —OCH2CONR1R2, C1-C6 straight chained alkyl, C1-C6 branched alkyl, C3-C6 cycloalkyl, halo-C1-C6 straight chain alkyl, halo-C1-C6 branched alkyl, halo-C3-C6 cycloalkyl, cyano-C1-C6 straight chain alkyl, cyano-C1-C6 branched alkyl, and cyano-C3-C6 cycloalkyl;
R1 and R2 are each independently selected from the group consisting of hydrogen, C1-C6straight chained alkyl, C1-C6 branched alkyl, C3-C6 cycloalkyl, halo-C1-C6 straight chain alkyl, halo-C1-C6 branched alkyl, halo-C3-C6 cycloalkyl, cyano-C1-C6 straight chain alkyl, cyano-C1-C6 branched alkyl, and cyano-C3-C6 cycloalkyl; and
R3 and R4 are each independently selected from the group consisting of hydrogen, C1-C6straight chained alkyl, C1-C6 branched alkyl, C3-C6 cycloalkyl, halo-C1-C6 straight chain alkyl, halo-C1-C6 branched alkyl, halo-C3-C6 cycloalkyl, cyano-C1-C6 straight chain alkyl, cyano-C1-C6 branched alkyl, and cyano-C3-C6 cycloalkyl, or wherein R3 and R4, taken together with a nitrogen atom to which they are attached, form a nitrogen-containing heterocycle, such nitrogen-containing heterocycle being optionally substituted with from one to three substituents independently selected from the group consisting of a straight or branched C1-C6 alkyl group, a halogen atom, a straight or branched C1-C6 alkoxy group, a straight or branched C1-C6 trihaloalkyl group, and a hydroxy group.
