Reaction Steps

A microwave tube was charged with (S)-4-((S)-5,5-dimethyl-2-oxo-4-phenyloxazolidin-3-yl)cyclohex-1-en-1-yl trifluoromethanesulfonate (0.205 g, 0.489 mmol), 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (0.120 g, 0.587 mmol), tetrakis(triphenylphosphine)palladium(0) (0.085 g, 0.073 mmol) and sodium carbonate (0.155 g, 1.466 mmol). Dioxane (1.70 mL) and water (0.25 mL) were added and the vial was charged with argon. The reaction mixture was heated to 100° C. with microwave for 1 h. The reaction mixture was purified via column chromatography on silica gel (RediSep 12 g column, gradient elution with 0% to 50% (90:10 CH2Cl2—MeOH—CH2Cl2) to afford (S)-5,5-dimethyl-4-phenyl-3-((S)-4-(pyridin-3-yl)cyclohex-3-en-1-yl)oxazolidin-2-one (0.128 g, 0.367 mmol, 75% yield) as a yellow oil.
