To a solution of 2-(4-((2-(3-chlorophenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)amino)phenyl)ethanol (0.175 g, 0.48 mmol) in methylene chloride (10 mL) was added Dess-Martin periodinate (0.304 g, 0.72 mmol). The mixture stirred at rt for 16 h. After this time, the reaction was quenched with water and a saturated solution of Na2S2O3 and then extracted with ethyl acetate. The organic layer were dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The residue was purified by column chromatography (silica, hexanes/ethyl acetate) to afford the title compound (0.114 g, 65%) as an orange oil. MW=363.84. 1H NMR (CDCl3, 500 MHz) δ 9.78 (t, J=2.3 Hz, 1H), 8.40-8.37 (m, 1H), 8.29-8.25 (m, 1H), 7.71 (d, J=8.5 Hz, 2H), 7.41-7.36 (m, 2H), 7.27-7.23 (m, 2H), 6.33 (s, 1H), 3.71 (d, J=2.3 Hz, 2H), 3.04 (t, J=7.5 Hz, 2H), 2.81 (t, J=7.5 Hz, 2H), 2.21 (quin, J=7.5 Hz, 2H); APCI MS m/z 364 [M+H]+.
