The mixture of 3-(piperidin-4-yl)-1H-indole hydrochloride (0.060 g; 0.253 mmol), 5-(2,5-difluorobenzyl)isoxazole-3-carboxylic acid (0.061 g; 0.253 mmol), HATU (N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate) (0.096 g: 0.253 mmol) and N,N-diisopropylethylamine (0.110 mL; 0.634 mmol) in DMF (3 mL) was stirred for 72 hours at room temperature and was concentrated under reduced pressure. The residue 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: 0 to 10% of ethyl acetate in dichloromethane) to give 0.069 g (65%) of (4-(1H-indol-3-yl)piperidin-1-yl)(5-(2,5-difluorobenzyl)isoxazol-3-yl)methanone as a white solid.
