Procedure

To a solution of 2-((S)-3-((S)-1-(4-bromophenyl)ethyl)-2-oxo-6-phenyl-1,3-oxazinan-6-yl)acetic acid (200 mg, 0.5 mmol) in anhydrous CH2Cl2 (10 mL) was added 1-aminopropan-2-one (119 mg, 0.7 mmol), HOBt (195 mg, 1.44 mmol), EDCl (283 mg, 1.44 mmol) and DIEA (620 mg, 4.8 mol) at 0° C. The formed mixture was stirred overnight at ambient temperature under nitrogen. Then the reaction mixture was washed with 1N aq HCl and water. The organic phase was dried over Na2SO4, filtered and concentrated to afford the residue, which was purified by prep TLC to give 2-((S)-3-((S)-1-(4-bromophenyl)ethyl)-2-oxo-6-phenyl-1,3-oxazinan-6-yl)-N-(2-oxopropyl)acetamide (118 mg, 50%). 1H NMR (400 MHz, CDCl3): δ=1.43 (d, 3H), 2.06 (s, 3H), 2.20 (m, 1H), 2.43 (m, 2H), 2.68 (m, 1H), 2.86 (m, 2H), 3.90 (m, 1H), 4.12 (m, 1H), 5.51 (m, 1H), 6.53 (m, 1H), 6.78 (m, 2H), 7.14 (m, 2H), 7.30 (m, 5H).
