Procedure
2-oxo-1-(4-(pyridin-3-yl)-2,3-dihydro-1H-inden-1-yl)-N-(pyridin-4-yl)-1,2-dihydropyridine-3-carboxamide was prepared by heating a mixture of 1-(4-bromo-2,3-dihydro-1H-inden-1-yl)-2-oxo-N-(pyridin-4-yl)-1,2-dihydropyridine-3-carboxamide (35.1 mg, 0.0855 mmol, 1.0 eq.), pyridin-3-ylboronic acid (12.8 mg, 0.104 mmol, 1.2 eq.), Pd(PPh3)4 (5.6 mg, 0.0048 mmol, 0.056 eq.), and potassium carbonate (15.1 mg, 0.109 mmol, 1.3 eq.) in 0.80 mL of dioxanes and 0.20 mL of H2O in a microwave at 140° C. for 5 min. The crude material was filtered through celite and the filtrate was purified by reverse phase HPLC using the method of 5-35% ACN/H2O in 40 min The purified material was concentrated and dried under vacuum to give 2-oxo-1-(4-(pyridin-3-yl)-2,3-dihydro-1H-inden-1-yl)-N-(pyridin-4-yl)-1,2-dihydropyridine-3-carboxamide as a clear colorless oil. Retention time (min)=8.051, method [8], MS (ESI) 409.2 (M+H); 1H NMR (300 MHz, CDCl3) δ 9.19 (m, 1H), 8.90 (m, 1H), 8.67 (m, 2H), 8.53 (m, 2H), 8.24 (d, J=7.1 Hz, 2H), 8.06 (m, 1H), 7.53 (m, 2H), 7.32 (m, 1H), 6.71 (t, J=7.7 Hz, 1H), 6.62 (t, J=7.1 Hz, 1H), 3.20 (m, 3H), 2.95 (m 1H), 2.19 (m, 1H).
