Participants

Reaction Steps

A solution of 2 g of 3-phenyl-6-benzofurancarboxylic acid in 100 ml of dichloromethane and 20 drops of acetic acid is treated with 3.0 g of dinitrogen tetroxide. The mixture is stirred for about 70 hours then evaporated to provide a residue. The residue is treated with cold 5% sodium hydroxide solution until solution occurs. The solution is acidified with 6N hydrochloric acid and the yellow solid is collected and recrystallized from ethanol to provide 2-nitro-3-phenyl-6-benzofurancarboxylic acid, m.p. 244°-247° C.
