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

To a solution of (S)-1,3-butanediol (807 mg) in DMF (10 mL) at 0C was added potassium t-butoxide (7.2 mL of a 1M solution in THF). After 1 h, the mixture was cooled to -20C and then 2-chloro-3-(4-methylsulfonyl)phenyl-5-trifluoromethylpyridine (1 g) was added as a solid. The resulting mixture was stirred for 24 h, warming to r.t. To the mixture was added saturated NH4Cl and the mixture was extracted with ethyl acetate. The organics were dried (MgSO4) and concentrated. Flash chromatography (1:1 hexane/ethyl acetate) provided the title compound as a white solid (323 mg).1H NMR (300 MHz, acetone-d6): d 1.15 (d, 3H), 1.75-2.00 (m, 2H), 3.15 (s, 3H), 3.65 (d, 1H), 3.85-4.00 (m, 1H), 4.60 (dd, 2H), 7.95 (d, 2H), 8.03 (d, 2H), 8.10 (d, 1H), 8.57 (d, 1H).
