Versuchsvorschrift

To a solution of 2-(4-((2-(3-chlorophenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)amino)phenyl)acetaldehyde (0.114 g, 0.31 mmol) in THF (10 mL) was added trimethyl(trifluoromethyl)silane (0.053 g, 0.38 mmol). The mixture stirred at 0° C. for 1 h after which tributylammonium fluoride (1.0 M, 0.078 mL, 0.078 mmol) was added. The mixture stirred at rt for 16 h. After this time, the reaction was diluted with water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The residue was purified by preparative HPLC (water/acetonitrile with 0.05% TFA) to afford the title compound (0.010 g, 7%) as a light yellow solid. MW=433.85. 1H NMR (DMSO-d6, 500 MHz) δ 8.82 (s, 1H), 8.30-8.22 (m, 2H), 7.75 (d, J=8.5 Hz, 2H), 7.56-7.49 (m, 2H), 7.31 (d, J=8.5 Hz, 2H), 6.20 (d, J=11.5 Hz, 1H), 4.23-4.12 (m, 1H), 2.95-2.85 (m, 4H), 2.76-2.68 (m, 1H), 2.10 (quin, J=7.5 Hz, 2H); APCI MS m/z 434 [M+H]+.
