Application of 1093879-46-9 , The common heterocyclic compound, 1093879-46-9, name is 2-(6-Bromopyridin-2-yl)acetic acid, molecular formula is C7H6BrNO2, 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.
Step 1 : to a solution of 2-(6-bromopyridin-2-yl)acetic acid (266 mg, 1 .23 mmol) in DMF (5 ml.) were added DMAP (150 mg, 1.23 mmol), EDCl.HCl (279 mg, 1 .35 mmol) and [4-methyl- 2-(piperidin-1 -yl)phenyl](5-methylfuran-2-yl)methanamine Ex.2 (350 mg, 1.23 mmol). The reaction mixture was stirred at rt. After completion of the reaction (monitored by TLC), sat. NH4CI was added and the solution was extracted with EtOAc. The organic layer was washed with sat. NH4CI, dried over MgS04, filtered and evaporated to dryness under reduced pressure. The crude material was purified by column chromatography on silica gel using Cyclohexane/EtOAc (70:30) as eluent to afford 2-(6-bromopyridin-2-yl)-N-{[4-methyl-2- (piperidin-1 -yl)phenyl](5-methylfuran-2-yl)methyl}acetamide (470 mg, 79%) as yellow oil. 1H NMR (300 MHz, DMSO-d6, d in ppm): 1.39-1 .59 (m, 6H), 2.17 (s, 3H), 2.26 (s, 3H), 2.52- 2.63 (m, 2H), 2.73-2.87 (m, 2H), 3.66 (s, 2H), 5.91 (d, 1 H, J=3.3Hz), 5.94 (dd, 1 H, J=3.0Hz, J=0.9Hz), 6.49 (d, 1 H, J=8.4Hz), 6.91 (d, 1 H, J=7.9Hz), 6.95 (s, 1 H), 7.20 (d, 1 H, J=7.8Hz), 7.35 (dd, 1 H, J=7.5Hz, J=0.6Hz), 7.49 (dd, 1 H, J=7.9Hz, J=0.7Hz), 7.68 (t, 1 H, J=7.4Hz), 8.86 (d, 1 H, J=8.4Hz).
The synthetic route of 1093879-46-9 has been constantly updated, and we look forward to future research findings.
