Reaction Steps

To a solution of tetrahydro-4-pyranol (0.36 g, 3.54 mmol) in DMF (5 mL) was added sodium hydride (60% dispersion, 0.17 g, 4.25 mmol). The resulting mixture was added to a solution of 2,4,5-trichloropyrimidine (650 mg, 3.5 mmol) in THF at 0° C. The combined mixture was then allowed to warm to room temperature. To the reaction was then added water and the product was extracted with a 1:1 EtOAc-Heptane mixture. The extract was then dried over Na2SO4, filtered and concentrated. The crude product was purified by column chromatography (0-30% EtOAc in heptane) to give 2,5-dichloro-4-(tetrahydro-2H-pyran-4-yloxy)pyrimidine. 1H-NMR (CDCl3): δ 8.33 (s, 1H), 5.42 (m, 1H), 4.09-3.90 (m, 2H), 3.65 (m, 2H), 2.19-1.99 (m, 2H), 1.87 (m, 2H).
