実験手順
A solution of 15 mL concentrated HF in 150 mL acetonitrile was added dropwise to a solution of [(2,4,6-triisopropyl-phenyl)-acetyl]-sulfamic acid 4-(tert-butyl-dimethyl-silanyloxy)-2,6-diisopropyl-phenyl ester (9.71 g, 15.4 mmol) in 400 mL acetonitrile at room temperature under a nitrogen atmosphere. Stirred for 16 hours and then concentrated in vacuo. The residue was partitioned between water and dichloromethane. The organic layer was dried over magnesium sulfate, filtered, and concentrated to give an oily solid. Trituration with hexanes gave 7.24 g of [(2,4,6-triisopropyl-phenyl)-acetyl]-sulfamic acid 4-hydroxy-2,6-diisopropyl-phenyl ester as a white solid; mp 182-183° C.
