Compounds of this invention increase plasma levels of high density lipoprotein or HDL, the “good” cholesterol and as such may be useful for treating diseases such as atherosclerosis. These compounds are represented by the formula
wherein:
R1, R2, and R3 are independently hydrogen, C1-C6 alkyl, phenyl or —(CH2)1-6 phenyl where phenyl is optionally substituted by halogen, cyano, nitro, C1-C6 alkyl, C1-C6alkoxy, trifluoromethyl, C1-C6 alkoxycarbonyl, —CO2H or OH;
R4 and R5 are independently hydrogen, C1-C10 alkyl, C3-C8 cycloalkyl, —(CH2)0-6Ar1 where Ar1 is phenyl, naphthyl, furanyl, pyridinyl or thenyl and Ar1 can be optionally substituted by halogen, cyano, nitro, C1-C6 alkyl, phenyl, C1-C6 alkoxy, phenoxy, trifluoromethyl, C1-C6 alkoxycarbonyl, —CO2H or OH, or R4 and R5 together with the nitrogen to which R4 and R5 are attached form a ring containing 4-7 carbon atoms;
and Ar is phenyl, naphthyl, furanyl, pyridinyl or thienyl which may be optionally substituted by halogen, cyano, nitro, C1-C6 alkyl, C3-C6 cycloalkyl, phenyl, C1-C6 alkoxy, phenoxy, trifluoromethyl, C1-C6 alkoxycarbonyl, —CO2H or OH.
