These common heterocyclic compound, 202925-07-3, name is 2-Chloro-1-fluoro-4-methoxybenzene, 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. Recommanded Product: 202925-07-3
A mixture of 3-chloro-4-fluoroanisole (2.52 g, 15.7 mmol, 1.0 eq.), silver trifluoroacetate (8.53 g, 38.6 mmol, 2.5 eq.), iodine (7.94 g, 31.3 mmol, 2.0 eq.) and chloroform (100 mL) is stirred at r.t. for 16h. The reaction mixture is filtered through a silica plug on a fritted funnel and rinsed with chloroform. The filtrate is washed successively with an aqueous solution of Na2S2O3, water and brine, dried over MgSO4, filtered and concentrated in vacuo. The residue is purified by flash chromatography on silica gel to afford the expected product
The synthetic route of 2-Chloro-1-fluoro-4-methoxybenzene has been constantly updated, and we look forward to future research findings.
