Reaktionsschritte
A mixture of 2-chloropyrimidin-5-ol (1 g, 7.66 mmol), chlorocyclopentane (2.39 mL, 22.98 mmol) and potassium carbonate (3.18 g, 22.98 mmol) in N,N-dimethylformamide were heated at 65° C. for 16 h at ambient temperature. Water was added and the mixture was extracted with ethyl acetate. The organic layer was washed with water and brine, dried over sodium sulfate and concentrated in vacuo. The residue was purified by column chromatography (0-25% ethyl acetate/hexanes) to afford 2-chloro-5-(cyclopentyloxy)pyrimidine (831 mg, 4.18 mmol, 54.6% yield) as a white solid. MS (LC/MS) R.T.=2.32; [M+H]+=199.23.
