Procedure

A solution of 5-[(6-aminopyridin-3-yl)oxy]-3-(4-methoxybenzyl)-3,4-dihydropyrido[2,3-d]pyrimidin-2(1H)-one (100.00 mg; 0.26 mmol; 1.00 eq.), 5-(4-fluoro-phenyl)-4-oxo-1,4-dihydro-pyridine-3-carboxylic acid (67.97 mg; 0.29 mmol; 1.10 eq.), pybop (179.26 mg; 0.34 mmol; 1.30 eq.), DMF (4.00 ml), and N,N-diisopropylethylamine (131.72 μl; 0.79 mmol; 3.00 eq.) was stirred at room temperature for 4 days. The reaction was concentrated, redissolved in DMSO, and purified via prep HPLC to afford 49 mg (26%) of 284 as a tan solid. LC-MS (M+H=593, obsd.=593).
