実験手順

Under inert gas atmosphere 28.4 mL (56.8 mmol) of a sodium-bis-(trimethylsilyl)-amide solution in THF (c=2 mol/L) are chilled to −17° C. and dropwise charged with 2.00 g (11.3 mmol) 2-bromo-6-fluoropyridine. Afterwards 2.14 g (22.7 mmol) dimethyl sulfone are added and the reaction mixture is stirred at −17° C. for 1 h. The reaction is quenched by the addition of aq. sat.NaCl solution and extracted with EtOAc. The organic layer is dried over MgSO4, filtered and the solvent is removed in vacuo.
