実験手順

A suspension of Example 314b (100 mg, 0.190 mmol), pyridin-3-ylboronic acid (23.31 mg, 0.190 mmol), sodium carbonate (60.3 mg, 0.569 mmol), and tris(dibenzylideneacetone)-dipalladium(0) (15.48 mg, 0.019 mmol) in 4 mL dioxane-water (3:1) was heated under nitrogen under microwave conditions (Biotage Initiator) at 120° C. for 30 minutes. The reaction mixture was the treated with 1 mL aqueous 4 N NaOH and heated at 120° C. under microwave conditions again for 30 minutes. The mixture was diluted with water and extracted with ethyl acetate (2×), washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated and the residue was purified by flash chromatography (silica gel, 0-10% methanol/dichloromethane gradient) to give the title compound (53 mg, 75% yield). 1H NMR (300 MHz, DMSO-d6) δ ppm 11.95 (s, 1H), 8.90 (dd, J=2.4, 0.7 Hz, 1H), 8.56-8.49 (m, 1H), 8.07 (ddd, J=8.0, 2.4, 1.7 Hz, 1H), 7.71-7.64 (m, 2H), 7.45 (ddd, J=7.9, 4.8, 0.8 Hz, 1H), 7.34 (s, 1H), 7.26 (t, J=2.7 Hz, 1H), 7.21 (d, J=8.5 Hz, 1H), 6.18 (dd, J=2.6, 2.2 Hz, 1H), 3.91 (d, J=6.7 Hz, 2H), 3.58 (s, 3H), 1.15-1.04 (m, 1H), 0.49-0.42 (m, 2H), 0.28-0.21 (m, 2H). MS (ESI+) m/z 372.2 (M+H)+.
