These common heterocyclic compound, 175278-29-2, name is Methyl 5-fluoro-2-methylbenzoate, 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. Computed Properties of C9H9FO2

A mixture of methyl 5-fluoro-2-methylbenzoate (0.5 g, 3.0 mmol),NBS (0.18 g, 3.0 mmol), and di-benzoyl peroxide (BPO) (36 mg, 0.15 mmol) in 1,2-dichloroethane (5 mL) was heated at 80 C for 12 huntil all starting material was consumed. The reaction was cooled to room temperature, and the precipitated solid was removed by filtration and washed with ethers (10 mL). The filtrate was concentrated in vacuo and the residue was partitioned between 2 N NaHCO3 (15 mL) and ethers (15 mL). The organic layer was separated, dried over MgSO4, filtered and concentrated to give a crude product (0.65 g, 89%), which was used in the next step reaction without further purification.
