Participants

Reaction Steps

The preparation is carried out analogously to the procedure of Example 27A using 1.4 g (3.41 mmol) of 2-(2-propoxyphenyl)-5-methyl-7-(2-ethylheptyl)-3H-imidazo-[5,1-f]-[1,2,4]-triazin-4-one (Example 20A). This gives 1.4 g (80.6%) of sulphonyl chloride as a white foam which is directly reacted further.
