Versuchsvorschrift

372.3 mg (1.1 mmol) of 8-cyclopentyl-2-(2-ethoxy-phenyl)-6-methyl-3H-imidazo [1,5-α][1,3,5]triazin-4-one (example IX) are added in portions to 0.66 ml (9.9 mmol) of ice-cooled chlorosulfonic acid. The mixture is subsequently stirred overnight at room temperature before being diluted with dichloromethane and poured onto ice water. The organic phase is separated off. The aqueous phase is extracted once again with dichloromethane and the organic phases are combined, dried and evaporated.
