Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 4856-97-7.

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. 4856-97-7, name is (1H-Benzoimidazol-2-yl)methanol, This compound has unique chemical properties. The synthetic route is as follows., COA of Formula: C8H8N2O

Preparation of (1-allyl-1H-benzoimidazol-2-yl)-methanol: To a solution of (1H-benzoimidazol-2-yl)-methanol (501 mg, 3.38 mmol) and allyl bromide (0.29 mL, 3.38 mmol) in DMF (15 mL) was added N,N-diisopropylethylamine (0.71 mL, 4.06 mmol). The reaction mixture was stirred at 60° C. overnight. Then the mixture was cooled to room temperature and quenched with saturated NaHCO3 (25 mL). Then it was extracted with CH2Cl2 (3*25 mL). The combined organic layer was washed with brine (2*25 mL), dried (MgSO4), filtered, concentrated, and dried in vacuo to afford a brown oil. Purification by flash column chromatography on silica gel using 2percent CH3OH/CH2Cl2 afforded the product as a yellow oil (180 mg, 28percent). 1H NMR (CDCl3) delta 4.85 (br s, 5H), 4.98 (d, 1H, J=17.1 Hz), 5.17 (d, 1H, J=10.5 Hz), 5.88-6.01 (in, 1H), 7.20-7.26 (m, 3H), 7.66 (t, 1H, J=3.9 Hz).

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 4856-97-7.
