Reaction Steps
The preparation is carried out analogously to the procedure of Example 27A using 400 mg (1 mmol) of 2-(2-ethoxyphenyl)-5-methyl-7-n-nonyl-3H-imidazo-[5,1-f][1,2,4]triazin-4-one (Example 24A) and 1.18 g (10 mmol) of chlorosulphuric acid. This gives 402 mg (80.1%) of sulphonyl chloride which is directly reacted further.
