Adding a certain compound to certain chemical reactions, such as: 32673-41-9, name is 4-Imidazolemethanol hydrochloride, 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 32673-41-9, HPLC of Formula: C4H7ClN2O
EXAMPLE 1 Ethyl 2-ethoxy-6-(4-(hydroxymethyl)imidazole-1-yl)-7-nitroquinoline-3-carboxylate To a solution of ethyl 2-ethoxy-6-fluoro-7-nitroquinoline-3-carboxylate (1.00 g, 3.24 mmol) in acetonitrile (10 ml) were added 4-(hydroxymethyl)imidazole hydrochloride (2.18 g, 16.2 mmol) and successively triethylamine (3 ml), and the mixture was stirred for 16 hours at 120 C. in a sealed tube under shading. After cooling, solvent was distilled off and the residue was submitted to silica gel column chromatography [dichloromethane-methanol(50:1?20:1)] under shading to obtain 583 mg of title compound as light brown powder. Yield 47%. 1H-NMR(DMSO-d6, delta): 1.35(3H,t,J=7.3 Hz), 1.42(3H,t,J=7.3 Hz), 4.38 (2H,q,J=7.3 Hz), 4.42(2H,d,J=6.8 Hz), 4.58(2H,d,J=7.3 Hz), 5.05(1H, t,J=5.4 Hz), 7.27(1H,s), 7.88(1H,s), 8.39(1H,s), 8.50(1H,s), 8.87 (1H,s).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Imidazolemethanol hydrochloride, other downstream synthetic routes, hurry up and to see.
