The important role of

Adding a certain compound to certain chemical reactions, such as: 3034-50-2, name is Imidazole-4-carbaldehyde, belongs to imidazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 3034-50-2, Computed Properties of C4H4N2O

A 22-L, four-neck, round-bottom flask equipped with a mechanical stirrer, a temperature probe, a condenser, and an addition funnel with a nitrogen inlet was charged with lH-imidazole-4-carboxaldehyde (Aldrich, 1.10 kg, 11.5 mol) and pyridine (3.0 L, 3.0 mol). The reaction flask was cooled to 8 C with an ice bath and hydroxylamine hydrochloride (871 g, 12.5 mol) was added slowly in portions to maintain the internal temperature below 30 C. The reaction was allowed to cool to ambient temperature and stirred for 2 h at ambient temperature. The resulting thick yellow solution was heated to 80 C with a heating mantle and acetic anhydride (2.04 L, 21.6 mol) was added dropwise over 200 min to maintain the temperature below 110 0C during the addition. The reaction EPO mixture was heated at 100 0C for 30 min, after which time it was allowed to cool to ambient temperature and then further cooled in an ice bath. The pH was adjusted to 8.0 (pH meter) by the addition of 25 wt % NaOH (5.5 L) at such a rate that the internal temperature was maintained below 30 C. The reaction mixture was then transferred into a 22-L separatory funnel and extracted with ethyl acetate (6.0 L). The combined organic layer was washed with brine (2 x 4.0 L), dried over MgSO4, filtered, and concentrated to dryness under reduced pressure at 35 0C to give the crude product as a yellow semisolid. The resulting semisolid was suspended in toluene (3.0 L) and stirred for 1 h, after which time it was filtered to give a light yellow solid, which was resuspended in toluene (3.0 L) and stirred for 1 h. The resulting slurry was filtered and the filter cake washed with toluene (2 x 500 mL) to give the title compound as a light yellow solid [870 g, 82%). The 1H and 13C NMR spectra were consistent with the assigned structure.
