Phenyl N-methylcarbamate (350 mg, Production example 2-1) was added to a solution of 4-(3-methyl-1H-5-indolyl)oxy-2-pyridinamine (500 mg), sodium hydride (93 mg) and N,N-dimethylformamide (5 ml) at room temperature; and the reaction mixture was stirred for 2 hours and 45 minutes. Water was added to the reaction mixture; extraction was performed with ethyl acetate; and purification was performed by NH-silica gel column chromatography (Fuji Silysia, hexane:ethyl acetate=1:2, sequentially, ethyl acetate) to yield the title compound as a pale yellow amorphous solid (365 mg).
