(Bis(2-methoxyethyl)amino)sulfur trifluoride → 6-(1-Acetyl-4,5-dihydro-1H-pyrrol-2-yl)-5-(4-(methanesulfonyl)phenoxy)-2-pyridin-2-yl-1H-benzimidazole

참여 물질

반응 단계

2 mg of bis(2-methoxyethyl)aminosulfur trifluoride was added to a chloroform (1 ml) solution of 2 mg of 1-acetyl-2-(5-(4-(methanesulfonyl)phenoxy)-2-pyridin-2-yl-1H-benzimidazol-6-yl)pyrrolidin-3-ol diastereomer A obtained in Example 469, and the reaction liquid was stirred at room temperature for 15 minutes. The solvent was evaporated away under reduced pressure, and the resulting residue was purified through partitioning thin-layer chromatography (Kieselgel™ 60F254, Art 5744 (by Merck), chloroform/methanol=15/1) to obtain the entitled compound as a colorless oily substance.
