Reaction Steps

A solution of (S)-3-((S)-1-(3-bromophenyl)ethyl)-6-(4-fluorophenyl)-6-(2-oxopropyl)-1,3-oxazinan-2-one (18.5 mg, 0.043 mmol) in dry toluene (3 mL) was cooled to 0° C. A solution of MeMgBr (3.0M in THF, 45 μL, 3 equiv) was added. After 15 min, the mixture was warmed to rt slowly and stirred 2 h. LC-MS found reaction completed. The reaction was quenched by satd aq NH4Cl solution (2 mL), diluted with EtOAc (10 mL), washed with 1% aq HCl (3 mL), brine (3 mL), and dried over Na2SO4. After filtration and concentration, the residue was purified by preparative HPLC to afford (S)-3-((S)-1-(3-bromophenyl)ethyl)-6-(4-fluorophenyl)-6-(2-hydroxy-2-methylpropyl)-1,3-oxazinan-2-one (8.0 mg, 42%). LC-MS (3 min) tR=1.75 min, m/z=472, 474 (M+Na); 1H NMR (CDCl3) 7.32-7.21 (m, 3H), 7.12-6.98 (m, 4H), 6.89 (m, 1H), 5.65 (q, 1H), 2.89 (m, 1H), 1.50 (d, 3H), 1.15 (d, 6H).
