Compounds of the formula
or pharmaceutically acceptable salts thereof wherein:
A is a bond, -(CH2)n- or -CH(B)-, where n is an integer of 1 to 3 and B is -CN, -CON(R9)R9' or -C02R7;
R1 is lower alkyl, aryl or arylalkyl;
R2 is hydrogen, hydroxy, alkoxy, -CH20H, cyano, -C(O)OR7 , -C02H, -CONH2, tetrazole, -CH2NH2 or halogen;
R3 is hydrogen, alkyl, heterocycle or
R4 is hydrogen, alkyl or B;
R5, R5', R8, R8' or R8'' are independently hydrogen, alkoxy, lower alkyl, halogen, -OH, -CN, -(CH2)-nNR6COR7, -CON(R6)R6', -CON(R6)OR6', -C02R6, -SR7, -SOR7, -S02R7, -N(R6)SO2R1, -N(R6)R6', -NR6COR7, -OCH2CON(R6)R6', -OCH2CO2R7 or aryl; or R5 and R5' or R8 and R8' may together with the carbon atoms to which they are attached form an aryl or heterocycle;
R6 and R6' are independently hydrogen or lower alkyl; and
R7 is lower alkyl;
R9 is hydrogen, lower alkyl, alkyl, cycloalkyl, arylalkyl, aryl, heteroaryl; or R9 and R9' may together with the nitrogen atom to which they are attached form a hetocycle; with the proviso that when A is a bond or -(CH2)n and R3 is hydrogen or unsubstituted alkyl, then R4 is B or substituted alkyl. These compounds are beta3 adrenergic receptor agonists and are useful, therefore for example, in the treatment of diabetes, obesity and gastrointestinal diseases.
