In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 624-76-0, name is 2-Iodoethanol belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Quality Control of 2-Iodoethanol
Example 58Preparation of Derivative 58 According to the Present InventionDerivative 58 having the following formula was prepared as follows. Sodium hydride (24.14 mg, 1.0 mmol, 60% dispersed oil) was added in 20 ml of DMF solution containing 5-4-(2-cyclohexylethoxy)benzylidene)thiazolidin-2,4-dione (200 mg, 0.60 mmol) and stirred at room temperature under nitrogen. The mixture was further stirred for 10 minutes, and 2-iodoethanol (123.81 mg, 0.72 mmol) dissolved in 5 ml of DMF was slowly added thereto. After being stirred at 60 C. for 48 hours, the reaction mixture was extracted with ethyl acetate and washed with water. The organic layer was dried with anhydrous magnesium sulfate, filtered and solvent-evaporated. The residue was purified by silica gel chromatography (hexane:ethyl acetate=10:1) to afford Derivative 58 having the above formula, 5-[(4-(2-cyclohexylethoxy)benzylidene]-3-(hydroxyethyl)-1,3-thiazolidine-2,4-dione (180 mg, yield: 79%).1H NMR (300 MHz, CDCl3) delta 7.878 (s, 1H), 7.485 (d, J=14.4 Hz, 2H), 7.007 (d, J=14.4 Hz, 2H), 4.078 (t, J=13.2 Hz, 2H), 4.001 (t, J=10.2 Hz, 2H), 3.891 (t, J=10.2 Hz, 2H), 2.049 (m, 1H), 1.670-1.782 (m, 7H), 1.471-1.529 (m, 1H), 1.178-1.284 (m, 3H), 0.956-1.034 (m, 2H)
The synthetic route of 624-76-0 has been constantly updated, and we look forward to future research findings.
