Reaction Steps

To a solution of methyl 2-(4-((S)-1-((R)-6-(3-(4-methoxybenzyloxy)propyl)-2-oxo-6-phenyl-1,3-oxazinan-3-yl)ethyl)phenyl)acetate (100 mg, 0.188 mmol) in THF (2 mL) was added methylmagnesium bromide (0.3 mL, 3 mol/L) at −78° C. The formed mixture was stirred for 3 h. The reaction was quenched by aqueous solution of NH4Cl. The organic phase was separated and concentrated to provide the crude product, which was purified by TLC to give (R)-3-((S)-1-(4-(2-hydroxy-2-methylpropyl)phenyl)ethyl)-6-(3-hydroxypropyl)-6-phenyl-1,3-oxazinan-2-one (10 mg, 10%). 1H NMR (CDCl3): δ=1.08 (d, 6H), 1.19 (m, 2H), 1.42 (d, 3H), 1.64 (m, 2H), 1.84 (m, 2H), 2.04-2.19 (m, 4H), 2.53 (s, 2H), 2.80 (m, 1H), 3.29 (t, 2H), 3.72 (s, 3H), 4.25 (s, 2H), 5.54 (q, 1H), 6.74 (m, 5H), 6.82 (m, 2H), 7.10 (m, 3H), 7.23 (m, 4H).
