Reference of 68282-47-3, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 68282-47-3, name is 2-Phenyl-1H-imidazole-4-carbaldehyde, This compound has unique chemical properties. The synthetic route is as follows.
Step 1 4-Formyl-2-phenyl-imidazole-1-carboxylic acid 4-nitro-benzyl ester 4-Formyl-2-phenylimidazole (624 mg) and sodium hydrogen carbonate (791 mg) were dissolved in dioxane (3.6 mL), THF (3.6 mL) and water (7.2 mL). The 48.7% solution of p-nitrobenzyl chloroformate (PNZCl) in dioxane (2.08 mL) was added to the mixture at room temperature and stirred for 2.5 h. The mixture was diluted with ethyl acetate and washed with brine. The organic layer was dried (MgSO4) and concentrated under reduced pressure. The residue was crystallized from ethyl acetate and n-hexane to give the title compound (956 mg, 75%). 1H NMR (delta, CDCl3) 5.41 (s, 2H), 7.32 (d, 2H, J=8.6 Hz), 7.40-7.51 (m, 3H), 7.56-7.58 (m, 2H), 8.17-8.20 (m, 2H), 8.22 (s, 1H), 9.97 (s, 1H).
The chemical industry reduces the impact on the environment during synthesis 2-Phenyl-1H-imidazole-4-carbaldehyde. I believe this compound will play a more active role in future production and life.
