Reaction Steps

In 50 ml. of chloroform was dissolved 5.4 g. of 4-hydroxy-3-nitroacetophenone and then 5 ml. of chloroform solution of 4.8 g. of bromine was added dropwise to the solution gradually. Thereafter, the mixture was stirred for 15 minutes and concentrated under a reduced pressure to form yellow crystals. By recrystallizing the product from benzene-n-hexane, 6.3 g. of the crystals of α-bromo-4-hydroxy-3-nitroacetophenone melting at 69°-71° C. were obtained.
