Abstract :Condensation of methylcrotonic acid with 4-chloro-o-phenylenediamine in 4N HCl yielded 5-chloro-2-insert ignore into journalissuearticles values(1-isobutenyl);benzimidazole and 7-chloro-4, 4-dimethyl-1,3,4,5-tetrahydro-2H-1,5-benzodiazepin-2-one. Methacrylic acid when condensed with o-phenylenediamine in 4N HCl yielded the already reported 3-methyl-1,2,4,5-tetrahydro-2H-1,5-benzodiazepin-2-one and 2insert ignore into journalissuearticles values(2-propenyl);benzimidazole. Condensation of methacrylic acid with 4-chloro-o-phenylenediamine in 4N HCl yielded 5-chloro-2insert ignore into journalissuearticles values(2-propenyl);benzimidazole. The structures of all the purified compounds were confirmed with the help of mass and 1H NMR spectral analysis.
