A mixture of EXAMPLE 11C (45.2 mg), (E)-3-phenylprop-1-enylboronic acid (21.1 mg), bis(triphenylphosphine)palladium(II) dichloride (catalytic), and 2M LiOH (0.3 mL) in 7/2/3 dimethoxyethane/ethanol/H2O (2 mL) was heated under microwave (CEM Discover) conditions at 150° C. for 30 minutes. The mixture was quenched with 1 MHCl (0.4 mL) and extracted with ethyl acetate. The extract was dried (MgSO4), filtered, and concentrated. The cruconcentrate was purified by reverse phaseHPLC (Zorbax SB-C18, 20-100% acetonitrile/water/0.1% trifluoroacetic acid). 1H NMR (500 MHz, DMSO-d6) δ 12.95 (brs, 1H), 11.44 (s, 1H), 8.34 (d, 1H), 7.88 (d, 1H), 7.54 (m, 2H), 7.44 (m, 2H), 7.31 (m, 5H), 7.18 (m, 3H), 6.83 (d, 1H), 6.00 (m, 2H), 4.08 (t, 2H), 2.21 (m, 2H).
