Participants

Reaction Steps

A solution of n-butyl-4-(4-benzyloxyphenoxy)-3-nitro-5-sulphamyl-benzoate (7.3 g) in 1N sodium hydroxide (120 ml) was heated on a steam bath for 45 minutes. After cooling and acidification by addition of 4N hydrochloric acid, the precipitated 4-(4-benzyloxyphenoxy)-3-nitro-5-sulphamyl-benzoic acid was isolated by filtration and recrystallized from aqueous ethanol. After drying, the compound was obtained with a melting point of 247°C.
