Reaction Steps

To a solution of cyclopentanol (0.287 g, 3.33 mmol) in THF (5 mL) was added sodium hydride (0.016 g, 0.67 mmol) and the mixture stirred at rt under a nitrogen atmosphere for 30 min. Then, the mixture was added treated with a solution of 4-chloro-2-(methylsulfonyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine (0.155 g, 0.67 mmol) dropwise in THF (2 mL) and the resulting mixture stirred at rt for 2 h. After this time, the reaction mixture was diluted with water and extracted with ethyl acetate. The combined organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The residue was purified by column chromatography (silica, hexanes/dichloromethane) to afford the title compound (0:080 g, 52%). MW=238.71. 1H NMR (CD3OD, 300 MHz) δ 5.64-5.40 (m, 1H), 2.90 (t, J=7.6 Hz, 2H), 2.78 (t, J=7.6 Hz, 2H), 2.21-2.08 (m, 2H), 1.90-1.71 (m, 4H), 1.71-1.59 (m, 2H), 1.38-1.18 (m, 2H); APCI MS m/z 239 [M+H]+.
