Reaction Steps

To a solution of isopropyl 3-amino-2-(4-((2-(3-chlorophenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)amino)benzyl)-3-oxopropanoate (0.090 g, 0.19 mmol) in THF (5 mL) was added lithium aluminum hydride (1.0 M, 0.38 mL, 0.38 mmol). The mixture stirred at 0° C. for 2 h. The mixture was quenched with water and sodium hydroxide (2M) 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, dichloromethane/methanol) to afford the title compound (0.020 g, 25%) as a white solid. MW=422.91. 1H NMR (DMSO-d6, 500 MHz) δ 8.77 (s, 1H), 8.30-8.21 (m, 2H), 7.70 (d, J=8.5 Hz, 2H), 7.55-7.49 (m, 2H), 7.23 (s, 1H), 7.18 (d, J=8.0 Hz, 2H), 6.73 (s, 1H), 4.67 (t, J=5.5 Hz, 1H), 3.59-3.52 (m, 1H), 3.43-3.36 (m, 1H), 2.94-2.84 (m, 4H), 2.79-2.56 (m, 3H), 2.10 (quin, J=7.5 Hz, 2H); APCI MS m/z 423 [M+H]+.
