Reaction Steps
Sodium hydride (0.591 g, 14.77 mmol) was added portionwise to a solution, of 3-(pyrrolidin-1-yl)propan-1-ol (1.615 g, 12.50 mmol) in THF (20 mL) at to 0° C. then stirred at ambient temperature for 30 minutes, 5-Bromo-2-fluoropyridine (2 g, 11.36 mmol) was added and the resulting mixture stirred at ambient temperature for 2 h before being quenched by the addition of a sat. aqueous solution of ammonium chloride. The moisture was extracted with EtOAc (2×100 mL), the organic layer dried, over Na2SO4, filtered and evaporated to afford pale yellow solid. The crude product was purified by FCC, elution gradient 0 to 10% MeOH in DCM, to afford the desired material (2.70 g, 83%) as a yellow solid. Mass Spectrum: m/z (ES+)[M+H]+=285.
