Versuchsvorschrift
3.00 g (8.00 mmol) of the sulfonamide prepared in Example 1 and 2.90 g (16.0 mmol) of 30% strength sodium methylate solution were stirred in 50 ml of methanol for 12 hours at room temperature, and then evaporated down in a rotary evaporator. Stirring the residue in H2O and acidifying with dilute HCl gave 2.30 g (81%) of the desired product in the form of colorless crystals (active ingredient 1.002).
