Procedure

A solution of N-methoxy-N-methylfuran-3-carboxamide (913 mg, 5.89 mmol) in anhydrous THF (10 mL) was cooled to −78° C. under nitrogen, and a solution of benzylmagnesium chloride in THF (2 mol/L, 3.53 mL) was added through a syringe. The reaction mixture was stirred at this temperature for 5 hours. TLC (PE:EtOAc=5:1) indicated reaction was nearly complete, saturated NH4Cl solution (20 mL) was added to quench the reaction, and the aqueous layer was extracted with EtOAc (80 mL). The organic layer was washed with brine (30 mL), dried over Na2SO4, filtered, and concentrated to afford 1-(furan-3-yl)-2-phenylethanone as a yellow oil (696 mg, yield: 63.2%).
