Procedimiento

Phenyl N-(4-(1-(methylamino)carbonyl-1H-indol-5-yloxy)-pyridin-2-yl)-N-(phenoxycarbonyl)carbamate (150 mg, 0.278 mmol, Production example 5-2) was dissolved in N,N-dimethylformamide (1.5 ml); 5N aqueous solution of sodium hydroxide (0.29 ml) and 1,1-dioxothiomorpholine hydrochloride (246 mg, 1.44 mmol) were added thereto; and the reaction mixture was stirred at room temperature for 5 hours. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (Fuji Silysia BW-300, ethyl acetate). Diethyl ether was added to this to allow to crystallize; and the crystals were filtered off, washed with diethyl ether, and dried under aeration to yield the title compound as colorless crystals (100 mg, 0.226 mmol, 78.5%).
