Reaction Steps

4.0 mm of (+)-2-bromo-3-methylbutyric acid is dissolved in a solvent consisting of 100 ml of ether, 100 ml of isobutylene, and 0.5 ml of sulfuric acid. The resulting solution is shaken for approximately 72 hours in an autoclave at room temperature. The solution is then neutralized with sodium bicarbonate, dried with magnesium sulfate, and then evaporated to yield (+)-t-butyl 2-bromo-3-methylbutyrate.
