Procedure

A solution of (S)-1-(2-(tert-butyldimethylsilyloxy)-1-(4-chloro-3-fluorophenyl)ethyl)-4-(2-(tetrahydro-2H-pyran-4-ylamino)pyrimidin-4-yl)pyridin-2(1H)-one (6.00 g, 10.7 mmol) in THF (20 mL) was treated with tetrabutyl ammonium fluoride (12.9 mL, 12.9 mmol) at room temperature for 30 minutes. The reaction mixture was concentrated, and the residue was taken up with ethyl acetate and water. The organic layer was washed with water (1×). The combined organics were dried, filtered and concentrated. The crude product was purified via column chromatography, eluting with ethyl acetate to give (S)-1-(1-(4-chloro-3-fluorophenyl)-2-hydroxyethyl)-4-(2-((tetrahydro-2H-pyran-4-ylamino))pyrimidin-4-yl)pyridin-2(1H)-one as a solid (4.14 g, 87%; 96% enantiomeric excess (“e.e.”) by chiral HPLC (Chiral Tech, column OJ-H, 4.6 mm×250 mm, 5u, 30% ethanol/70% hexanes, 1 mL/minute)). 1H NMR (400 MHz, CDCl3) δ 8.38 (d, J=5.0 Hz, 1H), 7.40 (m, 2H), 7.20 (m, 2H), 7.10 (d, J=8.2 Hz, 1H), 6.88 (d, J=5.0 Hz, 1H), 6.78 (m, 1H), 6.20 (m, 1H), 5.16 (d, J=8.0 Hz, 1H), 4.31 (m, 2H), 4.10 (m, 1H), 4.00 (m, 2H), 3.55 (m, 2H), 2.74 (br, s, 1H), 2.06 (m, 2H), 1.58 (m, 2H); m/z (APCI-pos) M+1=445.1, 447.0.
