Reaktionsschritte

To a flask purged with nitrogen was added Pd(tBu3P)2 (26 mg, 0.050 mmol), ZnF2 (52 mg, 0.50 mmol) and DMF (4 mL). The reaction mixture was allowed to stir for 10 minutes before benzyl 4-bromo-3-methoxy-benzoate (323 mg, 1.01 mmol) was added followed by trimethyl(2-methylprop-1-enoxy)silane (277 μL, 1.51 mmol). The reaction was heated at 80° C. overnight. The crude mixture was quenched with brine and extracted with EtOAc 3 times. The organic layer was dried over sodium sulfate and the solvent was evaporated to give benzyl 3-methoxy-4-(2-methyl-1-oxopropan-2-yl)benzoate. ESI-MS m/z calc. 312.4, found 313.4 (M+1)+; Retention time: 3.27 minutes (4 min run).
