Potassium tert-butoxide (1.85 g, 16.5 mmol) was added to a mixture of 5-bromo-2-chloropyridine (2.89 g, 15.0 mmol) and 1-propanol (1.230 mL, 16.5 mmol) in THF (15 mL). The reaction mixture was heated at 120° C. for 30 minutes in a microwave reactor. The mixture was poured into a mixture of water (50 mL) and EtOAc (100 mL). The organic layer was washed with brine, dried over MgSO4 and evaporated to dryness. Flash chromatography (silica, 0-20% EtOAc in heptanes) gave the title compound as a yellow oil (3.13 g, 97%) sufficiently pure for the next step.
