Reaction Steps

4M HCl in dioxane (0.939 mL, 3.76 mmol) was added to 1-((S)-2-(tert-butyldimethylsilyloxy)-1-(3-chlorophenyl)ethyl)-4-(2-(((3S,4S)-3-fluorotetrahydro-2H-pyran-4-yl)amino)pyrimidin-4-yl)pyridin-2(1H)-one (0.105 g, 0.188 mmol) in MeOH (5 mL). After 30 minutes, the reaction mixture was evaporated, and the residue was partitioned between EtOAc and saturated aqueous NaHCO3. The EtOAc was washed with brine, dried over MgSO4, filtered, and evaporated to yield a crude product (0.08 g) as a film. This was chromatographed on a 10 g Biotage SNAP column with 10:1 EtOAc/1-PrOH. Fractions 9-16 contained 1-((S)-1-(3-chlorophenyl)-2-hydroxyethyl)-4-(2-(((3S,4S)-3-fluorotetrahydro-2H-pyran-4-yl)amino)pyrimidin-4-yl)pyridin-2(1H)-one as a solid foam. 1H NMR (400 MHz, CD3OD) δ 8.38 (d, 1H), 7.80 (d, 1H), 7.41-7.39 (m, 1H), 7.38-7.28 (m, 2H), 7.22 (d, 1H), 7.09 (d, 1H), 7.00-6.97 (m, 1H), 6.15-6.11 (m, 1H), 4.83-4.70 (m, 1H), 4.34-4.25 (m, 2H), 4.20-4.15 (m, 1H), 4.01-3.98 (m, 1H), 3.94-3.88 (m, 1H), 3.70-3.54 (m, 2H), 2.08-1.95 (m, 1H), 1.83-1.77 (m, 1H) 1.13 (d, 1H); m/z (APCI-pos) M+1=445.1; 97.5% e.e. by chiral HPLC (Chiral Tech, column OD-H, 4.6 mm×250 mm, 5 u, 20% ethanol/80% hexanes, 1 mL/minute).
