Reaction Steps

To a solution of 2-bromomethyl-3-methyl-butyric acid (52.1 g, 0.267 mol) in dichloromethane (150 ml) was added concentrated sulphuric acid (2.85 ml) and isobutylene (150 ml). The mixture was stirred in a Parr vessel at room temperature for 24 hours. The mixture was slowly added to a saturated solution of sodium hydrogencarbonate (300 ml) and extracted with dichloromethane (50 ml). The organic layer was washed with brine (100 ml), separated, dried over magnesium sulphate, filtered and the solvent removed in vacuo to afford the title compound as a pale yellow oil (66.4 g, 99%).
