Participants

Reaction Steps

Phenyl N-(4-(1-(methylamino)carbonyl-1H-5-indolyloxy)-2-pyridyl)-N-(phenoxycarbonyl)carbamate (12.1 g, 23.2 mmol) synthesized in Production example 5-2 was dissolved in dimethylformamide (150 ml); 4-(1-pyrrolidinyl)piperidine (14.4 g, 93.3 mmol) was added thereto; and the reaction mixture was stirred at room temperature for 16 hours. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was washed with brine and concentrated to about 100 ml. The residue was allowed to be kept cool at 5° C. for overnight to precipitate crystals. The crystals were filtered off, washed with ethyl acetate to yield the title compound (7.8 g, 16.9 mmol, 73%) as white crystals.
