Procedure

Sodium carbonate (100 μl, 2M aqueous), (2-isopropoxy-5-methylphenyl)boronic acid (39 mg), and N-{[(3R)-1-(5-bromopyridin-2-yl)pyrrolidin-3-yl]methyl}-4-(5-cyano-7-isopropyl-1,3-benzoxazol-2-yl)benzamide (EXAMPLE 84, 27 mg) were dissolved in toluene (2.1 ml), water (0.6 ml) and ethanol (0.3 ml). To this solution was added tetrakis(triphenylphosphine)palladium(0) (9 mg). The mixture was heated to 150° C. for 25 min via microwave, and then cooled and concentrated. The residue was dissolved in dichloromethane and purified via flash chromatography on a Biotage Horizon, 40 M column, eluting with 1 column volume of 100% ethyl acetate in hexanes, followed by a gradient of 0 to 100% ethyl acetate in hexanes over 10 column volumes, followed by 4 column volumes of 100% ethyl acetate to provide the title compound (26 mg, 84%). Mass spectrum (ESI) 614.6 (M+2). 1H NMR (500 MHz, CDCl3): δ 8.37 (d, J=2.3 Hz, 1H), 8.34 (d, J=8.2 Hz, 2H), 7.95 (d, J=8.2 Hz, 2H), 7.94 (s, 1H), 7.72 (dd, J=8.6 Hz, 2.3 Hz, 1H), 7.52 (s, 1H), 7.09 (s, 1H), 7.04 (dd, J=8.4 Hz, 2.1 Hz, 1H), 6.87 (d, J=8.2 Hz, 1H), 6.43 (d, J=8.7 Hz, 2H), 4.40 (sept, J=6.1 Hz, 1H), 3.79 (m, 2H), 3.73 (m, 1H), 3.51 (m, 3H), 3.41 (m, 1H), 2.76 (sept, J=6.9 Hz, 1H), 2.32 (s, 3H), 2.27 (m, 1H), 1.91, (m, 1H), 1.46 (d, J=6.8 Hz, 6H), 1.24 (d, J=5.9 Hz, 6H).
