1.29 g (6.91 mmol) of methyl 2-acetylheptanoate (Example 16A) are hydrolysed to 2-acetylheptanoic acid according to Example 17A. The acid in 20 ml of dichloromethane is reacted analogously to Example 23A with 903 mg (6.90 mmol) of 1-hydroxy-1H-benzotriazole, 2.02 g (20 mmol) of 4-methylmorpholine, 1.32 g (6.90 mmol) of N′-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride and 890 mg (3.4 mmol) of 6-(1-aminoethyl)-3-(4-methoxybenzyl)-1,2,4-triazin-5(4H)-one (Example 10A) to give 2-acetyl-N-{1-[3-(4-methoxybenzyl)-5-oxo-4,5-dihydro-1,2,4-triazin-6-yl]ethyl}heptanamide.
