Procedure

N1-(2-Fluoroethyl)-5-[(2-amino-4-pyridyl)oxy]-1H-1-indolecarboxamide (500 mg), 1-tert-butyloxycarbonylpiperidine-4-carboxylic acid (440 mg), benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (Bop Reagent) (840 mg), triethylamine (0.44 ml) and dimethylformamide (10 ml) were stirred at room temperature for 17 hours. Water was added, extraction was performed with ethyl acetate, NH type silica gel was added to the extract, the solvent was distilled off under reduced pressure and the reaction product was adsorbed onto the silica gel. The silica gel was charged into a dry column packed with NH type silica gel, and column purification was performed (hexane:ethyl acetate=1:1). The solvent was distilled off under reduced pressure to obtain 160 mg of the target substance as a white powder.
