5'-BROMO-2'-HYDROXY-3'-NITROACETOPHENONE Chemical Properties,Usage,Production

Uses

5'-Bromo-2'-hydroxy-3'-nitroacetophenone is used as a chemical reagent in the synthesis of amides and benzoxazoles directly using a sulfate catalyst and microwaves. 1-(5-Bromo-2-hydroxy-3-nitrophen yl)ethanone is used in studies involving HIV-1 integrase inhibitors.

Preparation

Preparation by nitration of 5-bromo-2-hydroxyacetophenone in refluxing carbon tetrachloride (88%).

Synthesis

1450-75-5

70978-54-0

1. Synthesis of 5-bromo-2-hydroxy-3-nitroacetophenone To a solution of 5-bromo-2-hydroxyacetophenone (23.7 g, 0.110 mol) in carbon tetrachloride (90 mL) was slowly added concentrated nitric acid (17.2 mL). The reaction mixture was stirred at 75 °C for 50 min and subsequently cooled to room temperature. The precipitated solid was collected by filtration and washed with cold carbon tetrachloride. After vacuum drying, 20.9 g of the target product 5-bromo-2-hydroxy-3-nitroacetophenone was obtained as a light yellow solid in 73% yield. 1H NMR (300 MHz, CDCl3) δ: 2.73 (s, 3H), 8.14 (d, 1H), 8.31 (d, 1H), 12.92 (s, 1H).
