실험 절차

1.13 g of methyl 3-amino-4-(2-chloro-5-methoxy-phenoxy)-5-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-benzoate were dissolved in a mixture of toluene/pyridine (20 ml/30 ml) treated dropwise while cooling with ice with a solution of 1.05 g of 4-tert.butyl-benzenesulphonyl chloride in toluene (30 ml) and subsequently stirred at RT for 24 hours. The reaction mixture was poured on to ice/3M HCl, the product was extracted with ethyl acetate and the organic phase was dried over magnesium sulphate. After removing the solvent there was obtained methyl 3-(4-tert-butyl-benzenesulphonylamino)-4-(2-chloro-5-methoxy-phenoxy)-5-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-benzoate as a yellow solid.
