Procedure

To 31 g of 2,6-dichlorophenol in 120 ml acetic acid cooled in an ice bath is added over 5 minutes 50 ml of 70% nitric acid. After stirring an hour at room temperature, the mixture is purged with nitrogen, then poured into water, filtered; the product is washed with water and dried in vacuo to give 2,6-dichloro-4-nitrophenol. NMR (CD3OD): δ 8.2(s).
