88675-24-5,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.88675-24-5,Tetrahydrofuran-3-amine,as a common compound, the synthetic route is as follows.
Tetrahydrofuran amine (198mg, 1.92mmol) was dropwise added to (4S,5R)-5-[3,5- bis(trifluoromethyl)phenyl]-4-methyl-3-[(2-chloro-5-trifluoromethylpyridin-3-yl)met^ oxazolidin-2-one obtained in step 3. This reaction mixture was refluxed at 130¡ãC for 4 hrs with stirring, cooled to room temperature, diluted with ethyl acetate, and then extracted with water. The organic layer thus formed was washed with brine, dried over anhydrous magnesium sulfate, filtered, and concentrated. The residue was purified by chromatography to afford the title compound (130 mg, 36percent). 1 H NMR (400MHz, CDCI3) 8.36 (s, 1 H), 7.89 (s, 1 H), 7.71 (d, J = 2.8Hz, 2H), 7.36 (s, 1 H), 5.71 (d, J = 8.0Hz, 1 H), 4.68 (m, 2H), 4.13-3.97 (m, 4H), 3.90 (m, 2H), 3.76 (m, 2H), 2.33 (m, 1 H), 1.99 (m, 1 H), 0.88 (t, 3H), 0.80 (m, 3H).
The synthetic route of 88675-24-5 has been constantly updated, and we look forward to future research findings.
