Reaction Steps

To a solution of (R)-3-((S)-1-(4-(2-aminopyrimidin-4-yl)phenyl)ethyl)-6-(4-fluorophenyl)-6-(3-hydroxypropyl)-1,3-oxazinan-2-one (40 mg, 0.089 mmol) in CH3COOH (0.3 mL) and H2O (0.13 mL) was added an aqueous solution of NaNO2 (2 mol/L, 0.5 mL) dropwise at 0° C. The reaction was stirred for 10 min at this temperature before heating at 60° C. for 3 h. After the mixture was evaporated to dryness, the mixture was adjusted pH 9 with aqueous NaHCO3 solution. The mixture was extracted with EtOAc, and the organic layer was dried and concentrated to give the residue, which was purified by preparative TLC to give (R)-6-(4-fluorophenyl)-6-(3-hydroxypropyl)-3-((S)-1-(4-(2-hydroxypyrimidin-4-yl)phenyl)ethyl)-1,3-oxazinan-2-one (3.18 mg, 8%). LC-MS Method 2 tR=0.87 min, m/z=452. 1H NMR (CD3OD): 1.19-1.23 (m, 2H), 1.48 (d, 3H), 1.82-1.86 (m, 2H), 2.05-2.41 (m, 3H), 3.01-3.10 (m, 1H), 3.37 (t, 2H), 5.50 (q, 1H), 6.90 (d, 1H), 6.95-7.02 (m, 4H), 7.18-7.22 (m, 2H), 7.00-7.05 (m, 3H), 7.21-7.24 (m, 2H), 7.80 (d, 2H).
