実験手順
Oxalyl chloride (2.45 mL, 28 mmol) was added dropwise to a solution of 2,4,6-triisopropylphenyl acetic acid (5.66 g, 21.6 mmol) in 150 mL toluene with 4 drops of N,N-dimethylformamide as a catalyst. The resulting solution was stirred for 6 hours and then concentrated in vacuo. The residue was redissolved in 150 mL dichloromethane. 4-(Tert-butyl-dimethyl-silanyloxy)-2,6-diisopropylphenyl sulfamate (8.36 g, 21.6 mmol) and triethylamine (7.5 mL, 54 mmol) were added, and the resulting mixture was stirred overnight. Washed with 1M HCl, dried the organic layer over magnesium sulfate, filtered, and concentrated to give 9.86 g of [(2,4,6-triisopropyl-phenyl)-acetyl]-sulfamic acid 4-(tert-butyl-dimethyl-silanyloxy)-2,6-diisopropyl-phenyl ester.
