Reaction Steps

A mixture of (R)-3-((S)-1-(4-(6-chloropyrimidin-4-yl)phenyl)ethyl)-6-(4-fluorophenyl)-6-(3-hydroxypropyl)-1,3-oxazinan-2-one (20 mg, 0.0426 mmol) in 15% aq NaOH (5 mL) was heated to 110° C. overnight. Then the solvent was evaporated, and the residue was washed with EtOAc. The solid was filted off and the filtrate was dried, and condensed in vacuum to give the crude product, which was purified by preparative HPLC to afford (R)-6-(4-fluorophenyl)-6-(3-hydroxypropyl)-3-((S)-1-(4-(6-oxo-1,6-dihydropyrimidin-4-yl)phenyl)ethyl)-1,3-oxazinan-2-one (15 mg, 78%). LC-MS Method 2 tR=0.91 min, m/z=452, 408. 1H NMR (CD3OD): δ=1.31 (m, 1H), 1.59 (m, 3H), 1.95 (m, 2H), 2.25 (m, 1H), 2.35 (m, 1H), 2.46 (m, 1H), 3.15 (m, 1H), 3.48 (m, 2H), 5.59 (m, 1H), 6.81 (s, 1H), 7.12 (m, 4H), 7.33 (m, 2H), 7.79 (m, 2H), 8.25 (s, 1H).
