Procedure

To a solution of (R)-6-(2-aminoethyl)-3-((S)-1-(2′,4′-difluorobiphenyl-4-yl)ethyl)-6-(4-fluoro-phenyl)-1,3-oxazinan-2-one stirred in anhydrous CH2Cl2 (5 ml) was added HOBT (36 mg, 0.264 mmol), EDCl (52 mg, 0.264 mmol), DIEA (0.5 ml) and hydroxy-acetic acid (50.1 mg, 0.66 mmol) at 0° C. under N2 atmosphere. The solution was stirred at rt overnight. Then the solvent was removed under reduced pressure to give the residue, which was purified by preparative HPLC to afford N-(2-((R)-3-((S)-1-(2′,4′-difluorobiphenyl-4-yl)ethyl)-6-(4-fluorophenyl)-2-oxo-1,3-oxazinan-6-yl)ethyl)-2-hydroxyacetamide (19.2 mg, 28.6%). 1H NMR (CDCl3): 1.49-1.50 (d, 3H), 2.01-2.13 (m, 1H), 2.14-2.15 (m, 3H), 2.17 (m, 1H), 2.97-2.98 (m, 2H), 3.46-3.52 (m, 4H), 4.01-4.02 (m, 2H), 5.60-5.61 (m, 1H), 6.82-6.88 (m, 2H), 6.98-7.04 (m, 3H), 7.17 (s, 1H), 7.19-7.22 (m, 3H), 7.25-7.27 (m, 3H).
