Procedure

A mixture of 10 g of 3-bromo-2-oxooxolane, 6.6 g of benzylamine, 21 g of potassium carbonate and 200 mL of acetonitrile was stirred at 70° C. for 1 hour 30 minutes. Thereafter, 7.9 mL of 4-methylbenzoyl chloride was added dropwise to the reaction mixture at a temperature of 5° C. to 10° C., and the obtained mixture was then stirred at room temperature for 2 hours. Thereafter, 400 mL of ethyl acetate and 200 mL of water were added to the reaction mixture. The organic layer was fractionated. The obtained organic layer was successively washed with 100 mL of water and 100 mL of a saturated sodium chloride aqueous solution, and it was then dried over anhydrous sodium sulfate. The solvent was distilled away under reduced pressure, and the obtained residue was then dissolved in 100 mL of ethyl acetate under heating. After that, 100 mL of hexane was added dropwise to the reaction mixture at 50° C. A solid was collected by filtration, so as to obtain 11.2 g of N-benzyl-4-methyl-N-(2-oxooxolan-3-yl)benzamide.
