Reaktionsschritte
A mixture of 1,3-dibromobenzene (1.0 eq.), 3-hydroxy-3-methyl-butan-2-one (1.0 eq.), Pd2(dba)3 (0.02 eq.), xantphos (0.04 eq.) and t-BuONa (1.1 eq.) in THF (0.15M) was stirred at 60° C. for 2 h, poured in saturated aqueous NH4Cl and extracted with EtOAc (2×). The combined organic extracts were washed with brine, dried over Na2SO4, filtered and concentrated. Flash chromatography (Hex:EtOAc; 7:3) afforded the title compound as an oil.
