Procedure
To a mixture of 10 g of (2-furylcarbonyl)methylamine hydrochloride, 12.5 g of sodium bicarbonate, 200 ml of ethyl acetate and 100 ml of water are dropwise added 12.0 g of 4-chlorobenzoyl chloride at a temperature below 10° C. under stirring. The mixture is stirred at room temperature for 3 hours. Then, the ethyl acetate layer is collected, washed with water and dried. Said ethyl acetate layer is evaporated under reduced pressure to remove solvent. 16.0 g of N-(4-chlorobenzoyl)-(2-furylcabonyl)methylamine are thereby obtained. Yield: 98.2%
