Reaction Steps

A mixture of Example 226E (160 mg, 0.32 mmol), dibutyl vinylborate (88 mg, 0.48 mmol), CsF (146 mg, 0.96 mmol), Pd(PPh3)4 (37 mg, 0.03 mmol), DME (3.2 mL) and methanol (1.6 mL) was purged with argon, sealed in a vial and microwaved at 150° C. for 240 seconds. The mixture was diluted with ethyl acetate (50 mL), washed with brine, dried (Na2SO4), filtered, concentrated and purified on a Biotage silica gel cartridge (40 g) with 10% ethyl acetate/hexanes to provide the desired product. MS (ESI(+)) m/e 446 (M+H)+, 463 (M+NH)+, 468 (M+Na)+; (ESI(−)) m/e 444 (M−H)−; 1H NMR (300 MHz, DMSO-d6) δ 10.36 (s, 1H), 7.76 (m, 3H), 7.38 (m, 7H), 7.10 (d, 1H), 6.93 (dd, 1H), 5.86 (d, 1H), 5.51 (d, 1H), 5.26 (s, 2H).
