3-Chloroaniline → HCID 67338426, compound

Participants

Reaction Steps

Thionyl chloride (0.83 mL, 6.6 mmol) was added portionwise to a suspension of (E)-3-(3-hydroxy-4-nitro-phenyl)-acrylic acid (1.05 g, 5.0 mmol) in DCM-DMF (20-2 mL). After stirring the resulting solution at RT for 1.5 hrs, 3-chloro-aniline (2.12 mL, 20 mmol) was added dropwise and the mixture was stirred at RT for additional 2 hrs. Then the reaction mixture was diluted with DCM and washed with water, aqueous hydrochloric acid, and brine. The organic layer was dried over sodium sulphate and evapored. The resulting raw material was purified first by column chromatography (eluant DCM/MeOH), yielding 1.25 g of the title compound.
