Participants

Reaction Steps

The preparation is carried out analogously to the procedure of Example 27A using 0.34 g (0.96 mmol) of 2-(2-ethoxyphenyl)-5-ethyl-7-cyclopentyl-3H-imidazo-[5,1-f][1,2,4]-triazin-4-one (Example 16A). This gives 0.43 g (98%) of sulphonyl chloride as a colourless foam which is directly reacted further.
