Reaction Steps

A solution of 2-((S)-3-((S)-1-(4′-fluorobiphenyl-4-yl)ethyl)-2-oxo-6-(thiophen-2-yl)-1,3-oxazinan-6-yl)acetic acid (218 mg, 0.5 mmol) in THF anhydrous (10 mL) was added BH3 (3.0 mL) at 0□ and then stirred at reflux for 2 h. Then the reaction mixture quenched by water and separated, extracted with EtOAc twice. The organic phases was dried over Na2SO4, filtered and concentrated to afford the residue, which was purified by TLC to give (S)-3-((S)-1-(4′-fluorobiphenyl-4-yl)ethyl)-6-(2-hydroxyethyl)-6-(thiophen-2-yl)-1,3-oxazinan-2-one (85 mg, 40%). LC-MS Method 3 tR=1.35, min, m/z=426, 448; 1H NMR (CD3OD): 1.50 (m, 3H), 2.15 (m, 2H), 2.30 (m, 1H), 2.40 (m, 1H), 2.60 (m, 1H), 3.15 (m, 1H), 3.45 (m, 1H), 3.70 (m, 1H), 5.60 (m, 1H), 6.90 (m, 1H), 7.00 (m, 1H), 7.10 (m, 4H), 7.35 (m, 3H), 7.55 (m, 2H).
