Versuchsvorschrift

To a solution of 3-bromo-2-fluoropyridine (0.93 g, 5.28 mmol) in THF (5 mL) was added dropwise isopropylmagnesium chloride (2.64 mL, 5.28 mmol, 2M solution) at room temperature. After overnight stirring, dihydro-2H-pyran-4(3H)-one (0.486 mL, 5.28 mmol) was added dropwise. Reaction was quenched with saturated NH4Cl solution and extracted with DCM. Purification by Biotage (0-10% MeOH/DCM) produced the desired product.
