150 ml of epichlorohydrin are added, at ambient temperature, to a solution of 0.376 mol (73.7 g) of 3-nitro-4-acetylaminophenol in 375 ml of 1.1N sodium hydroxide solution. The reaction medium is left to stand at ambient temperature for 48 hours, with thorough stirring, and the expected product which has precipitated is then filtered off. After drying in vacuo and recrystallisation from benzene, this product melts at 123° C.
