Procedure
It is contemplated that 6-(4-aminophenyl)-1,3-dihydro-5-methyl-2H-imidazo[4,5-b]pyridin-2-one can be alkylated by reacting it with formic acid followed by reduction of the intermediate formylamino derivative to obtain 6-[4-(methylamino)phenyl]-1,3-dihydro-5-methyl-2H-imidazo[4,5-b]pyridin-2-one [I; Ar=4-CH3NHC6H4, R1 and R3 =H, R5 =CH3 ]; or by reacting it with formaldehyde under reducing conditions to obtain 6-[4-(dimethylamino)phenyl]-1,3-dihydro-5-methyl-2H-imidazo[4,5-b]pyridin-2-one [I; Ar=4-(CH3)2NC6H4, R1 and R3 =H, R5 =CH3 ].
