225 μl (2.22 mmol) of 4-methylmorpholine are added to a solution of 600 mg (2.22 mmol) of (3-cyanophenylamino)-2-fluorophenylacetic acid, 453 mg (2.22 mmol) of 1-(4-amino-2-methylphenyl)piperidin-2-one, 426 mg (2.22 mmol) of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (DAPECI) and 300 mg (2.22 mmol) of hydroxybenzotriazole hydrate (HOBt) in 1 ml of DMF, and the mixture is stirred at room temperature for 24 hours. The reaction mixture is introduced into water, and the precipitate is filtered off, giving 2-(3-cyanophenylamino)-2-(2-fluorophenyl)-N-[3-methyl-4-(2-oxopiperidin-1-yl)phenyl]acetamide as a colourless solid; ESI 456.
