Procedure

The nitro functionality of 3-(2,6-dichloro-4-nitro-phenoxy)-quinoline (4) was catalytically reduced under hydrogen with 5% weight/weight (catalyst/compound 4) of a 1% platinum/2% vanadium on carbon catalyst suspension in ethyl acetate at 0° C. The material was heated to 20° C., filtered through Celite. The Celite was washed with THF, and the filtrates were combined and evaporated to give 3,5-dichloro-4-(quinolin-3-yloxy)-phenylamine (5) in 98% yield.
