Reaktionsschritte

To a stirred solution of 1-(5-bromopyrimidin-2-yl)ethanone (100 mg, 0.5 mmol) in THF (10 mL) at −78° C. was added methylmagnesium bromide (1.4M solution, 3.6 mL, 5 mmol). The reaction mixture was stirred for an additional 20 minutes until LC/MS analysis indicated that the reaction was complete. Quenching with saturated NH4Cl, extraction with EtOAc and drying over MgSO4, afforded the crude residue which was taken forward as is in the next step.
