Versuchsvorschrift

A 450 mg (1.007 mmol) portion of ′N-(tert-butoxy)-2-({[4-(2-butynyloxy)phenyl]sulfonyl}amino)-2-(4-hydroxyphenyl)acetamide was stirred in neat TFA at room temperature for 72 h. TFA was removed in vacuo. The residue was chromatographed on preparative TLC, eluting with 1% HOAc and 10% MeOH in dichloromethane to provide 33.8 mg (9%) of 2-({[4-(2-butynyloxy)phenyl]-sulfonyl}amino)-N-hydroxy-2-(4-hydroxyphenyl)acetamide as a white solid. Electrospray Mass Spec 391.4 (M+H)+
