Reaction Steps

Analogously to Example 7A, 20.0 g (86.7 mmol) of 2-(3,4-dimethoxyphenyl)ethanamidine hydrochloride (Example 5A) are reacted with 5.21 g (104 mmol) of hydrazine hydrate and 24.3 g (130 mmol) of ethyl 3-(acetylamino)-2-oxobutanoate (Example 6A) to give N-{1-[3-(3,4-dimethoxybenzyl)-5-oxo-4,5-dihydro-1,2,4-triazin-6-yl]ethyl}acetamide.
