Fun Route: New Discovery of 24621-61-2

A chemical reaction often occurs in steps, although it may not always be obvious to an observer. Thank you very much for taking the time to read this article. If you are also interested in other aspects of (S)-Butane-1,3-diol, CAS: 24621-61-2, you can also browse my other articles.

Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.24621-61-2, name is (S)-Butane-1,3-diol, below Introduce a new synthetic route. , 24621-61-2

Example 63 (R)-3- {2-CHLORO-4- [3- (4-CHLORO-2-PHENOXY-PHENOXY)-BUTOXY]-PHENYL}-PROPIONIC acid Step A (S) -Acetic acid 3-hydroxy-butyl ester; A mixture of (S)- (+)-1, 3-butanediol (10.0 g, 0.1 mol) and 2,4, 6-collidine (27 g, 0.2 mol) in DCM (100 mL) is cooled to-78 C. The reaction is then treated dropwise with acetyl chloride (10.4 g, 0.13 mol), and stirred for 2hr AT-78 C. The reaction is then allowed to warm to rt and stir for an additional hour. The reaction is then quenched with IN HCl and extracted with DCM. The organic layer is separated, washed with brine, and dried over NA2SO4. The organic is filtered, and the solvent is removed to afford 9.77 g (66%) of acetic acid 3-hydroxy-butyl ESTER. IH NMR (400 MHz, CDC13) ; MS (ES+) NILZ mass calcd for C6HI203 132, found 133 (M + 1)., 24621-61-2
