Reaktionsschritte

To a mixture of K2CO3 (1.58 g, 11.5 mmol), 2,2-dimethylpent-4-enoic acid (1.30 g, 10.1 mmol) and DMF (8.1 mL) was added benzyl bromide (1.40 g, 8.19 mmol) slowly over 15 minutes. After 4 hours the mixture was diluted with a mixture of water (80 mL) and diethylether (80 mL). The organic layer was separated and sequentially washed with 80 mL of 5% aqueous sodium bicarbonate, saturated copper sulfate, slightly acidic water, half-saturated brine, and then saturated brine. The organics were then dried over sodium sulfate, filtered and concentrated in vacuo to give the title compound which was used without further purification. MS: m/z=219 (M+1).
