Synthetic Route of 94088-46-7, These common heterocyclic compound, 94088-46-7, name is 2-Fluoro-6-methoxybenzonitrile, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
In a round bottom flask, 5 cm3 water,0.453 g of 2-fluoro-6-methoxybenzonitrile (0.003 mol), 0.621 g of 1-(4-nitrophenyl)piperazine (0.003 mol), 0.387 gof DIPEA (0.003 mol), 0.096 g of TBAB (0.0003 mol), and 0.318 g of Na2CO3(0.003 mol) was taken. Reaction was carried out at reflux for 3 h. Then reaction mixture was cooled and extracted with ethyl acetate. The product was purified by flash chromatography on silica using hexane-ethyl acetate mobile phase to afford 0.42 g 16 (42%). M.p.:160-164 C; 1H NMR (400 MHz, CDCl3):delta = 3.939 (s, 4H),3.649 (s, 4H), 3.953 (s, 3H), 6.630 (d, J = 4 Hz, 2H), 6.893(d, J = 8 Hz, 2H), 7.460 (t, J = 8 Hz, 1H), 8.165 (d, J = 8 Hz,2H) ppm; 13C NMR (100 MHz, CDCl3):delta = 46.1 (CH2), 46.8(CH2), 47.2 (CH2), 50.9 (CH2), 56.1 (OCH3), 104.8 (CCN),110.5 (CH), 112.9 (CH), 115.7 (CN), 129.9 (CH), 134.4(CH), 138.8 (CNO2), 154.7 (C), 156.6 (C), 163.0 (CO) ppm; IR (KBr): =nu 2886, 2215, 1594, 1480, 1322, 1600, 1508,1458, 1266 cm-1; ESI-MS: m/z = 339 (MH+).
The synthetic route of 94088-46-7 has been constantly updated, and we look forward to future research findings.
