Procedure

Ethyl 4-(piperidin-4-yl)butyrate (650 mg, 2.0 mmol, Production example 43-2) was suspended in N,N-dimethylformamide (3.35 ml); phenyl N-(4-(1-(methylamino)carbonyl-1H-indol-5-yloxy)-pyridin-2-yl)-N-(phenoxycarbonyl)carbamate (350 mg, 0.67 mmol, Production example 5-2) was added; and the reaction mixture was stirred at room temperature for 1 hour. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was dried over anhydrous magnesium sulfate, concentrated under reduced pressure. The residue was purified by silica gel column chromatography (Fuji Silysia BW-300, hexane-ethyl acetate-methanol system) to yield the title compound (271 mg, 0.54 mmol, 80%) as a pale yellow oil.
