HCID 572900004-[3-(2-Pyridyl)-2-propenoyl)benzaldehyde Diethyl Acetal

Procedure

By the same method N-methylpyrrole-2-carbaldehyde and 1-benzyl imidazole-2-carbaldehyde are converted to 4-[3-(1-methyl-2-pyrrolyl)-2-propenoyl]benzaldehyde diethyl acetal and 4-[3-(1-benzyl-2-imidazolyl)-2-propenoyl]benzaldehyde.
