Versuchsvorschrift

To a solution of Intermediate X (0.280 g, 0.65 mmol) and (5-formyl-2-furyl)boronic acid (0.0912 g, 0.65 mmol) in 5 mL degassed DMF was added TPPTS (0.111 g, 0.20 mmol) Pd(OAc)2 (0.015 g, 0.07 mmol) and diisopropylamine (0.066 g, 0.65 mmol). After 15 h at rt, the reaction was diluted with satd. aqueous NaHCO3 and EtOAc, and the layers were separated. The organics were washed with brine, dried over Na2SO4, filtered and concentrated. Purification by normal phase chromatography (50->100% EtOAc/hexanes) afforded the desired coupled adduct. 1H NMR (400 MHz, CDCl3) δ 9.67 (s, 1H), 8.09 (m, 1H), 7.95 (m, 1H), 7.84 (m, 1H), 7.41-7.34 (m, 3H), 7.08 (m, 2H), 6.99 (d, J=5.9 Hz, 1H), 6.54 (d, J=7.5 Hz, 1H), 5.31 (m, 1H), 3.40 (s, 3H), 2.89 (s, 3H), 1.65 (d, J=7.0 Hz, 3H). LCMS [M+H]+=445.
