1.18 g (5.91 mmol) of methyl 2-acetyloctanoate (Example 18A) are hydrolysed to 2-acetyloctanoic acid according to Example 19A. The acid in 20 ml of dichloromethane is reacted analogously to Example 23A with 800 mg (5.90 mmol) of 1-hydroxy-1H-benzotriazole, 1.66 g (16.4 mmol) of 4-methylmorpholine, 1.13 g (5.9 mmol) of N′-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride and 900 mg (3.5 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}octanamide.
