Related Products of 1261609-83-9, These common heterocyclic compound, 1261609-83-9, name is 2-Bromo-5-(hydroxymethyl)benzonitrile, 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 B: Preparation of 2-bromo-5-(chloromethyl)benzonitrile [00231] To a magnetically stirred mixture of 2-bromo-5-(hydroxymethyl)benzonitrile (0.5 g, 2.358 mmol) in dry DCM (11.79 ml) at ice-bath tetmperatures was added thionyl chloride (0.344 ml, 4.72 mmol) in a dry 50 mL round-bottomed flask. DMF (0.5 mL) was added to aid solubilization. The reaction mixture was stirred at reduced temperature for 15 min and then was allowed to warm to rt. After 1 h, GC-MS analysis indicated the reaction was complete. The reaction mixture was diluted with DCM and sat’d aq. NaHC03, then stirred vigorously for 30 min. The layers were separated, the aq layer was extracted again with DCM, and the combined DCM extracts were dried over sodium sulfate, and filtered through a phase separator. The DCM was evaporated to afford 485 mg (56%) of the title compound as a white wax. H NMR (400 MHz, CDCI3) delta 7.70 (d, J = 3.8 Hz, 1H), 7.68 (d, J = 2.1 Hz, 1H), 7.48 (dd, J = 8.4, 2.3 Hz, 1H), 4.54 (s, 2H). 13C NMR (101 MHz, CDC13) delta 137.70, 134.03, 133.82, 133.60, 125.14, 116.62, 116.36, 43.93. GC-MS m z 231.
The synthetic route of 1261609-83-9 has been constantly updated, and we look forward to future research findings.
