Synthetic Route of 20850-43-5, 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. 20850-43-5, name is 5-(Chloromethyl)benzo[d][1,3]dioxole, This compound has unique chemical properties. The synthetic route is as follows.
5-Chloromethyl benzo [1,3]dioxol g, 65.7 mmol) was dissolved in Dimethylformamide. Then, potassium carbonate (18.2 g, 131.4 mmol), sodium iodide (10.8 g, 72.27 mmol) and ethyl benzoylacetate (12.5 mNo., 72.27 mmol) were added thereto and stirred for 5 hours at room temperature. The reaction mixture was extracted with ammonium chloride and ether, the organic layer was separated, dried over anhydrous magnesium sulfate, concentrated, and the resulting residue was purified by column chromatography to obtain 2- benzo [1,3]dioxol-5-ylmethyl-3-oxo-3-phenylpropionate ethyl ester (16.4 g, 76 %). ¹H NMR (200MHz, CDCl3) : No. 7.98-6.69 (m, 3H), 5.90 (s, 2H), 4.56 (t, J=7.4 Hz, 1H), 4.09 (q, J=7.2 Hz, 2H), 3.26 (d, J=7.4 Hz, 2H), 1.13 (t, J=7.2 Hz, 3H).
The chemical industry reduces the impact on the environment during synthesis 5-(Chloromethyl)benzo[d][1,3]dioxole. I believe this compound will play a more active role in future production and life.
