Reaction Steps

The preparation is carried out analogously to the procedure of Example 27A using 0.3 g (0.88 mmol) of 2-(2-ethoxyphenyl)-5-methyl-7-pentyl-3H-imidazo[5,1-f][1,2,4]triazin4-one (Example 21A). This gives 0.3 g (77.6%) of sulphonyl chloride as a white foam which is directly reacted further.
