Reaction Conditions

Reaction Steps

Into a DMF solution (150 ml) containing 4-amino-3-nitrophenol (4.72 g) were added successively potassium carbonate (12.8 g), tetrabutylammonium iodide (0.56 g) and 3-chloromethylpyridine hydrochloride (5.42 g), followed by about 1.5 hours of heating at 60° C. The reaction solution was concentrated under reduced pressure, ice-water (250 ml) and 1M hydrochloric acid aqueous solution (30 ml) were poured thereto, and the formed crystals were collected by filtration and dried to obtain 2-nitro-4-(pyridin-3-ylmethoxy)aniline (7.39 g). Hereinafter, the compounds of Reference Examples 35 and 60 were obtained similarly.
