Reaction Steps
To a mixture of vinyltributyltin (Aldrich, 65.0 mg, 0.21 mmol), ethyl ((1S)-5-{2-[2-(3-bromophenyl)-5-methyl-1,3-oxazol-4-yl]ethoxy}-2,3-dihydro-1H-inden-1-yl)acetate (50 mg, 0.10 mmol), and [1,1′-bis(diphenylphosphino)-ferrocene]dichloropalladium(II), complex with dichloromethane (1:1) (4.2 mg, 0.005 mmol) was added toluene (2 mL). The resulting solution was degassed with argon for 30 minutes, and then stirred at 110° C. for 16 h. The reaction mixture was cooled to rt and diluted with 10 mL ethyl acetate. The organic layer was filtered through a silica plug and the filtrate concentrated under reduced pressure. The crude was then redissolved in methanol and filtered through a silica-octyl plug before preparative HPLC purification using 30 to 100% acetonitrile in water (0.1% TFA) gradient to afford the desired product. 1H NMR (CD2Cl2) δ 8.03 (s, 1H), 7.86 (d, 1H), 7.39-7.51 (m, 2H), 7.04 (d, 1H), 6.68-6.84 (m, 3H), 5.88 ( (d, 1H), 5.31-5.35 (m, 1H), 4.10-4.23 (m, 4H), 3.48 (qr, 1H), 2.97 (t, 2H), 2.64-2.89 (m, 3H), 2.29-2.42 (m, 5H), 1.69-1.76 (m, 1H), 1.26 (t, 3H).
