Reaction Steps
To a solution of (−)-3-(4-bromophenyl)-1-(2-methylpyridin-4-yl)-3-o-tolylpropan-1-one (120 mg; example 142, step 2), oxazole (126 mg) and tetrakis(triphenylphosphine) palladium(0) (68 mg) was added lithium tert-butoxide (141 mg) and the reaction mixture heated by microwave irradiation to 120° C. for 30 min. The reaction mixture was extracted over a sat. solution of sodium hydrogencarbonate (50 mL) with ethyl acetate (3×50 mL) and the combined organic phases dried over sodium sulfate. The crude reaction product was purified by silica gel chromatography using a MPLC system (CombiFlash Companion, Isco Inc.) eluting with a gradient of n-heptane/ethyl acetate (1:1 to 2:1) to give the title compound as a colorless oil. MS (ESI+): m/z=383.0 ([M+H]+).
