327-52-6, name is 1-Bromo-2,4,5-trifluorobenzene, belongs to bromides-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. Quality Control of 1-Bromo-2,4,5-trifluorobenzene
In an oven-dried flask, dried halogen-group-containing compounds (2.3 equiv) were added to dry THF containing magnesium metal (Mg) (2.3 equiv, with glass pieces to activate the magnesium metal) at room temperature under nitrogen. The reaction mixture was stirred vigorously until Grignard generation occurred. The lactone (1 equiv dissolved in 40 mL of THF) was added dropwise to the Grignard reagent solution, and the mixture was stirred at room temperature for 16 h and monitored by TLC. The mixture was treated with saturated aqueous NH4Cl (20 mL) and then extracted with AcOEt (3¡Á10mL). The combined organic phases were dried over Na2SO4 and the solvent was removed by an evaporator. The residue was purified by silica-gel column chromatography (AcOEt/hexane). In another experiment, the ring-opening reactions of homoserine lactone with select Grignard reagents were carried out using 2.7 equiv ArMgBr at r.t. and 50C for 2 h.
The synthetic route of 327-52-6 has been constantly updated, and we look forward to future research findings.
