실험 절차

To a solution of 4,6-dichloro-2-methylsulfonyl-pyrimidine (3.41 g, 15 mmol) and (1S,4S)-2-oxa-5-azabicyclo[2.2.1]heptane hydrochloride (2.03 g, 15.0 mmol) in N,N-dimethylacetamide (40.5 mL), was added N,N-diisopropylethylamine (6.60 mL). The resulting mixture was stirred at room temperature. After 30 min, the reaction mixture was concentrated to a solid. The crude material was purified by column chromatography using an 80 g column, with a gradient of 0% to 100% ethyl acetate in heptane. The combined fractions containing product were concentrated under reduced pressure to provide (1S,4S)-5-(6-chloro-2-methylsulfonyl-pyrimidin-4-yl)-2-oxa-5-azabicyclo[2.2.1]heptane (3.03 g). 1H NMR (400 MHz, Chloroform-d) δ 6.30 (s, 1H), 3.98-3.81 (m, 3H), 3.45-3.35 (m, 2H), 3.28 (s, 3H), 2.16-1.98 (m, 2H), 1.95-1.86 (m, 1H).
