Electric Literature of 261723-33-5 , The common heterocyclic compound, 261723-33-5, name is (2-Bromo-6-fluorophenyl)methanol, molecular formula is C7H6BrFO, 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.
Pyridinium -toluenesulfonate (0.612 g; 2.43 mmol ) was added to a solution of 2- bromo-6-fluorobenzyl alcohol (5 g; 24.38 mmol ) and 3,4-dihydro-2H-pyran (3.34 mL; 36.58 mmol) in DCM (50 mL) at rt. The reaction mixture was stirred at rt for 12 h. The mixture was washed with brine, dried over MgSO.i, filtered and evaporated to give 7.67 g (quant.) of intermediate 234. This compound was used in the next step without any purification.
The synthetic route of 261723-33-5 has been constantly updated, and we look forward to future research findings.
