Participants

Reaction Steps

The [6-[(4-chlorophenylsulfonyl)(2,5-difluorophenyl)methyl]pyridin-3-yl]carboxylic acid (90 mg, 0.21 mmol) obtained in Example 50, a tetrahydrofuran solution (2.0M, 0.21 ml, 0.42 mmol) of dimethylamine, 4-(dimethylamino)pyridine (15 mg, 0.12 mmol) and triethylamine (0.045 ml, 0.32 mmol) were dissolved in dichloromethane (5 ml). To the resulting solution was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (61 mg, 0.32 mmol) at room temperature, followed by stirring at room temperature for 14 hours. The residue obtained by concentrating the reaction mixture under reduced pressure was subjected to flash silica gel chromatography. The fraction obtained from the hexane:ethyl acetate=2:1 eluate was concentrated under reduced pressure to give the title compound (35 mg, 0.066 mmol, 90%) as a white powder.
