Reaction Steps
To a suspension of sodium hydride (1.2 g of 60% suspension in mineral oil, hexane-washed, 30.3 mmol) in 40 mL of tetrahydrofuran was added diethyl carbonate (3.7 mL, 30.3 mmol) and 3-acetyl benzonitrile (2.2 g, 15.2 mmol). The resulting suspension was stirred at 65° C. for 1 h and then was cooled to room temperature. There was added 40 mL of 10% aqueous HCl and the reaction mixture was diluted with ethyl acetate and the layers were separated. The organic layer was washed with brine, dried (MgSO4) and concentrated in vacuo to afford 3.2 g (96%) of the title compound, which was sufficiently pure to be used without purification. MS(NH3—CI) 218.3 (M+H)+.
