Reaktionsschritte

Cyclohexanol (3.99 mL) was added to a mixture of NaH (60%, 1.50 g) in N,N-dimethylacetoamide (10 mL) at 0° C. The mixture was stirred at room temperature for 30 min. The solution of 5-bromo-2-chloropyridine (6.00 g) in N,N-dimethylacetoamide (10 mL) was added and the mixture was stirred at 100° C. for 1.5 hr. The mixture was quenched with water at room temperature and extracted with EtOAc. The organic layer was separated, washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by column chromatography (silica gel, eluted with EtOAc in hexane) to give the title compound (7.67 g) as colorless oil.
