Reaction Steps

To a mixture of 1-(4-chloro-2,3-dihydro-1H-inden-1-yl)-2-oxo-N-(pyridin-4-yl)-1,2-dihydropyridine-3-carboxamide (200 mg, 1.0 eq) in DME (4 mL) was added phenylboronic acid (3.5 eq), Pd(PPh3)2Cl2 (0.2 eq) and aqueous Na2CO3 (2M, 2 mL). The mixture was stirred at 120° C. for 30 mins by microwave. At the end of reaction 50 mL of H2O was added and extracted with ethyl acetate. The combined organic layer was washed with brine and dried over MgSO4, evaporated the filtrate to give the crude product, which was purified by HPLC to afford 2-oxo-1-(4-phenyl-2,3-dihydro-1H-inden-1-yl)-N-(pyridin-4-yl)-1,2-dihydropyridine-3-carboxamide (21 mg, 10%).
