Reaction Steps

To a solution of methyl 4-((S)-1-((R)-6-(3-hydroxypropyl)-2-oxo-6-phenyl-1,3-oxazinan-3-yl)ethyl)benzoate (60 mg, 0.25 mmol) in THF (5 mL) was added NaBH4 (48 mg, 1.25 mmol). The mixture was heated to reflux for 15 minutes. Then methanol (3 mL) was added. The mixture was heated to reflux overnight. The reaction was quenched with water, and the solvent was removed. The aqueous layer was extracted with EtOAc for 3 times. The combined organic layer was washed with brine, dried over Na2SO4, and concentrated to give the crude product, which was purified by preparative TLC to give (R)-3-((S)-1-(4-(hydroxymethyl)phenyl)ethyl)-6-(3-hydroxypropyl)-6-phenyl-1,3-oxazinan-2-one (5 mg, 5%). LC-MS Method 2 tR=1.29, min, m/z=370, 392; 1H NMR (CDCl3): 1.33 (m, 1H), 1.45 (m, 3H), 1.64 (m, 1H), 1.90 (m, 2H), 2.11-2.24 (m, 2H), 2.81 (m, 1H), 3.50 (m, 2H), 4.52 (s, 2H), 5.58 (m, 1H), 6.82 (m, 2H), 7.03 (m, 2H), 7.25 (m, 5H).
