実験手順

13.4 mg of 4-(methanesulfonyl)phenol and 44.9 mg of cesium carbonate were added in order to an N-methyl-pyrrolidinone (2 ml) solution of 15 mg of N-(4-(1-acetyl-4-methylpyrrolidin-2-yl)-5-fluoro-2-nitrophenyl)pyridine-2-carboxamide, and the reaction liquid was stirred at 90° C. for 1 hour. 43.8 mg of tin chloride dihydrate was added to the reaction liquid, then heated up to 100° C. and stirred for 2 hours. The reaction liquid was dissolved in ethyl acetate, washed with aqueous saturated sodium bicarbonate, and dried with anhydrous sodium sulfate. 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=9/1) to obtain the entitled compound as a white solid.
