24621-61-2, An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.19132-06-0, name is (2S,3S)-Butane-2,3-diol. Here is a downstream synthesis route of the compound 19132-06-0
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).
