Reaktionsschritte
tetrahydro-2H-pyran-4-ol (850 mg, 8.32 mmol) was dissolved in DMF (10 mL), cooled to 0° C., NaH (500 mg, 10.4 mmol) was added and stirred for 45 minutes at room temperature, then 5-bromo-2-chloropyridine (2 g, 10.4 mmol) was added and the mixture was stirred overnight at 60° C. The mixture was poured into water, extracted by EA, the organic layer was washed by brine, dried over Na2SO4, concentrated and purified by flash chromatography, gave 1.7 g white solid. MS: (m/z): 258 (M−H)+, 260 (M+H)+
