461-17-6, name is 1,1,1-Trifluoro-4-iodobutane, belongs to iodides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Application In Synthesis of 1,1,1-Trifluoro-4-iodobutane
The alcohol of Example A12 (0.50 g, 1.23 mmol), tetrabutylammonium bromide (79 mg, 0.246 mmol), and KOH (207 mg, 3.69 mmol) were slurried in xylene (5 mL). Afterward, 4,4,4-trifluoromethyl-1-iodobutane (0.88 g, 3.69 mmol) was added, and the resulting mixture was stirred in a sealed vial at 80 C. over the weekend. Subsequently, the mixture was filtered through celite and concentrated under N2. Chromatography (on silica, ethyl acetate/hexanes) afforded the ether in the form of a colorless oil (296.4 mg, 46.7% yield). NMR(CDCl3) delta 1.25-1.42 (m, 7H), 1.52 (s, 9H), 1.55 (d, 2H), 1.67 (d, 2H), 1.75-1.84 (m, 2H), 2.06-2.24 (m, 4H), 2.32 (d, 2H), 2.92 (t, 2H), 3.40 (t, 2H), 3.38 (t, 2H), 3.43 (t, 2H), 3.72-3.82 (m, 2H), 3.95 (dd, 2H). ESMS m/z=516.44 (M+H)+.
The synthetic route of 461-17-6 has been constantly updated, and we look forward to future research findings.
