This invention relates to intermediates useful in the production of substituted pyridopyrimidinones of general formula (I):
wherein
n is 0 to 3;
R1 and R2 are, independently, H, C1-C6alkyl, hydroxy(C1-C6alkyl), formyl, carbonyl(C1-C6alkyl), carboxy, or carboxy(C1-C6alkyl);
R3 and R4 are, independently, H, C1-C6alkyl, or hydroxy;
R3a and R4a are H, or one of -CR3R3a and -CR4R4a is a carbonyl group;
with the proviso that at least one of the groups R1 and R2 must be hydroxy(C1-C6alkyl), formyl, carbonyl(C1-C6alkyl), carboxy, or carboxy(C1-C6alkyl); or one of R3 and R4 must be hydroxy; or one of -CR3R3a and -CR4R4a must be a carbonyl group; ;
Ar1 is
wherein W is H, C1-C6alkyl, halogen, hydroxy, or C1-C6alkoxy;
Ar2 is
wherein X is
wherein R5 is H, CH3, tert-butyl, tri-n-butylstannyl, or triphenylmethyl; or a tautomer of said compound,
or a pharmaceutically acceptable salt of said compound or tautomer.
The compounds of Formula I are useful for treating hypertension and congestive heart failure. Also disclosed are pharmaceutical compositions containing compounds of Formula I and a pharmaceutically acceptable carrier and methods for production of the compounds of Formula I. Intermediates for making the pharmaceutical useful compounds are also enclosed.
