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., COA of Formula: C10H8N2O

a 4-Aminomethyl-2-phenylimidazole dihydrochloride Hydroxylamine hydrochloride (229 mg, 3.3 mmol) was added to a suspension of 2-phenylimidazole4-carboxaldehyde (516 mg, 3 mmol; prepared according to J. Chem. Soc. Perkin Trans. I 1974, 1527) and sodium acetate (541 mg, 6.6 mmol) in absolute EtOH (5 mL) and H2 O (5 mL) at RT. A yellow, homogeneous solution was produced. After 15 min, the reaction was concentrated on the rotavap to remove the EtOH, and the oily, aqueous mixture was extracted with 20% MeOH/CHCl3 (10 mL) then with CHCl3 (10 mL). The combined organic layers were dried (MgSO4) and concentrated to leave a yellow foam. The yellow foam was dissolved in absolute EtOH (9 mL), and 1.0 N HCl (6 mL, 6 mmol) and 10% Pd/C (0.32 g, 0.3 mmol) were added. The mixture was shaken on a Parr apparatus at RT under H2 (50 psi) for 4 h, then was filtered through Celite. The filtrate was concentrated on the rotavap to leave a light yellow solid. Recrystallization fron absolute EtOH/H2 O gave the title compound as a light pink solid (465 mg, 63%): mp 273-275 C. (dec.); 1 H NMR (250 MHz, CD3 OD) delta 7.93-8.12 (m, 2H), 7.80 (s, 1H), 7.50-7.76 (m, 3H), 4.40 (s, 2H); MS (ES) m/e 347.2 (2M+H)+, 174.0 (M+H)+, 157.0 (M+H–NH3)+.
