Methyl 2-bromoisobutyrate is used as carboxylate organic matter and can be used as intermediate in organic synthesis. Bromoisobutyric acid (4.17g, 25mmol) was dissolved in a solution of concentrated sulfuric acid (0.75mL) and methanol (50mL) and stirred under reflux for 2 hours. The solution is then cooled to room temperature and vacuum concentrated. The residue was dissolved in ether and washed with 10% sodium bicarbonate aqueous solution, washed with salt water, dried with magnesium sulfate, and vacuum concentrated again. Colorless oil was obtained (4.2g,23mmol,93% yield).
