Participants

Reaction Steps

A mixture of bis(5-chloro-2-hydroxy-3-nitrophenyl)methyl alcohol (4.5 g) and thionyl chloride (50 ml) was heated under reflux for 3 hr. Dimethylformamide (0.1 g) was added to the reaction mixture and the mixture was heated under reflux for a further hour. Excess thionyl chloride was then removed by distillation under reduced pressure and the remaining red oil was crystallised from ethanol to give 4 g of bis(5-chloro-2-hydroxy-3-nitrophenyl)methyl chloride, m.p. 180° C.
