Versuchsvorschrift

(S)-1-(2-(tert-Butyldimethylsilyloxy)-1-(4-chloro-3-fluorophenyl)ethyl)-4-(2-((2-methylpyrimidin-4-yl)amino)pyrimidin-4-yl)pyridin-2(1H)-one (0.034 g, 0.060 mmol) was placed in THF (5 mL) at room temperature. Tetra-n-butylammonium fluoride (“TBAF”) (0.18 mL, 0.18 mmol) was added to the mixture. The mixture was stirred for 1 hour, then poured into water, and extracted with DCM. The combined organic fractions were dried (MgSO4), filtered, and concentrated to give the crude product, which was purified by column chromatography (0-5.5% MeOH in DCM) to give the product (S)-1-(1-(4-chloro-3-fluorophenyl)-2-hydroxyethyl)-4-(2-((2-methylpyrimidin-4-yl)amino)pyrimidin-4-yl)pyridin-2(1H)-one (0.005 g, 18% yield). m/z (APCI-pos) M+1=453.
