In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 624-76-0 as follows. COA of Formula: C2H5IO
Example 396 (Z)-3-(2-Hydroxyethyl)-5-[{7-(4-methoxyphenyl)furo[3,2-c]pyridin-2-yl}methylene]thiazolidine-2,4-dione Step 1: Synthesis of 3-(2-hydroxyethyl)thiazolidine-2,4-dione Thiazolidinedione (12.8 mmol), 2-iodoethanol (15.1 mmol), potassium carbonate (17.4 mmol) and tetrabutylammonium iodide (1.3 mmol) were placed in acetone (25 ml), and stirred at 40 C. for 10 hours. The reaction mixture was cooled to room temperature, filtered through Celite, and concentrated under reduced pressure to yield brown oil. The residue thus obtained was purified by silica gel column chromatography (n-hexane/ethyl acetate=4/1, v/v) to obtain the title compound as colorless oil (yield: 54%). 1H NMR (CDCl3, 400 MHz) delta 4.00 (s, 2H), 3.85 (brs, 4H), 1.94 (brs, 1H)
According to the analysis of related databases, 624-76-0, the application of this compound in the production field has become more and more popular.
