実験手順

A mixture of 2-(5-chloro-2-(triethylsilyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)ethanamine (0.128 g; 0.413 mmol), 5-(2,5-difluorobenzyl)isoxazole-3-carboxylic acid intermediate 74 (0.104 g; 0.434 mmol), HATU (N,N,N′,N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate) (0.165 g: 0.434 mmol) and N,N-diisopropylethylamine (0.108 mL; 0.619 mmol) in DMF (3 mL) was stirred overnight at room temperature and concentrated under reduced pressure. The crude material was dissolved in dichloromethane and the organic layer was washed with water and concentrated under reduced pressure. The crude material was purified by flash chromatography on silica gel (eluent: 1 to 10% of ethyl acetate in dichloromethane) to give 0.108 g (49%) of N-(2-(5-chloro-2-(triethylsilyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)ethyl)-5-(2,5-difluorobenzyl)isoxazole-3-carboxamide as a solid.
