실험 절차

3-((R)-3-((S)-3,3-dimethylbutan-2-yl)-6-(4-fluorophenyl)-2-oxo-1,3-oxazinan-6-yl)propanoic acid (50 mg, 0.144 mmol), EDCI (55 mg, 0.28 mmol), HOBt (38 mg, 0.28 mmol), and DIEA (90 mg, 0.07 mmol) were dissolved in CH2Cl2 (10 mL) under ice bath. The mixture was stirred under an NH3 atmosphere overnight. The reaction mixture was concentrated to give the crude product, which was purified by preparative TLC to give 3-((R)-3-((S)-3,3-dimethylbutan-2-yl)-6-(4-fluorophenyl)-2-oxo-1,3-oxazinan-6-yl)propanamide (15 mg, 30%). LC-MS Method 1 tR=2.027, min, m/z=351.1; 1H NMR (CDCl3) 0.73 (s, 9H), 1.12 (d, 3H), 1.89-1.98 (m, 1H), 2.01-2.12 (m, 1H), 2.22-2.38 (m, 3H), 2.48-2.52 (m, 1H), 2.71 (m, 1H), 3.18 (m, 1H), 4.46 (m, 1H), 5.29 (s, 1H), 5.53 (s, 1H), 7.07 (m, 2H), 7.29 (m, 2H)
