実験手順

To a solution of 3-(N-(tert-butoxycarbonyl)-N-methylsulfamoyl)-thiophene-2-carboxylic acid (Int. 34) (150 mg, 0.467 mmol) in DCM (5 ml), (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide (196 mg, 0.467 mmol), EDC (268 mg, 1.400 mmol) and DMAP (28.5 mg, 0.233 mmol) were added and the mixture was reacted at RT overnight. The solvent was removed and the crude was purified by flash chromatography on silica gel (DCM/MeOH=95/5) affording (S)-4-(2-(3-(N-(tert-butoxycarbonyl)-N-methylsulfamoyl)thiophene-2-carbonyloxy)-2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy) phenyl)ethyl)-3,5-dichloropyridine 1-oxide (Int. 35) (230 mg, 0.318 mmol, MS/ESI+722.8 [MH]+).
