Reaktionsschritte
A solution of 4-acetylamino-N-tert-butylbenzenesulfonamide (8.0 g, 29.6 mmol), KOH (8.30 g, 148 mmol), H2O (6 mL) and MeOH (24 mL) is heated at 100° C. for 2 h. H2O (24 mL) is added and the mixture is heated for two more hours. It is allowed to cool, H2O is added and it is brought to pH 8 with 1N HCl. It is then extracted with EtOAc, dried over Na2SO4 and the solvent is removed, to give 6.0 g of the product as a white solid (yield: 89%).
