Reaction Steps
The preparation is carried out analogously to the procedure of Example 27A using 300 mg (0.84 mmol) of 2-(2-ethoxyphenyl)-5-methyl-7-n-hexyl-3H-imidazo-[5,1-f][1,2,4]-triazin-4-one (Example 23A) and 0.98 g (8.4 mmol) of chlorosulphuric acid. This gives 300 mg (78.7%) of sulphonyl chloride which is directly reacted further.
