Procedure
Analogously to Example 1, 530 mg (1.04 mmol) of 2-acetyl-N-{1-[3-(3,4-dimethoxybenzyl)-5-oxo-4,5-dihydro-1,2,4-triazin-6-yl]propyl}-5-phenylpentanamide and 610 mg (4.00 mmol) of phosphorus oxychloride are reacted to give 7-(1-acetyl-4-phenylbutyl)-2-(3,4-dimethoxybenzyl)-5-ethylimidazo[5,1-f][1,2,4]triazin-4(3H)-one.
