Reaction Steps

To a solution of 3-((R)-6-(4-fluorophenyl)-2-oxo-3-((S)-1-(4-(2,2,2-trifluoroethoxy)phenyl)ethyl)-1,3-oxazinan-6-yl)propanoic acid (145 mg, 1.37 mmol) in CH2Cl2 (5 mL) was added HOBt (167 mg, 1.24 mmol), EDCl (243 mg, 1.24 mmol) and DIEA (194 mg, 1.55 mmol) under NH3 at 0° C. The mixture was stirred at rt overnight. 1N HCl was added and the mixture was extracted with CH2Cl2. The organic layer was dried and concentrated to give the residue, which was purified by preparative HPLC to give 3-((R)-6-(4-fluorophenyl)-2-oxo-3-((S)-1-(4-(2,2,2-trifluoroethoxy)phenyl)ethyl)-1,3-oxazinan-6-yl)propanamide (21 mg, 15%). LC-MS Method 2 tR=1.16 min, m/z=491, 469, 425. 1H NMR (CDCl3, 400 MHz): 1.43 (d, 3H), 1.88-1.95 (m, 1H), 2.07-2.19 (m, 5H), 2.40 (m, 1H), 2.83 (m, 1H), 4.21 (m, 1H), 5.18 (s, 1H), 5.33 (s, 1H), 5.56 (m, 1H), 6.64 (d, 2H), 6.85 (d, 2H), 6.97 (t, 2H), 7.17 (m, 2H).
