실험 절차

A solution of 5-[(3-amino-1-methyl-1H-indazol-6-yl)oxy]-3-(4-methoxybenzyl)-3,4-dihydropyrido[2,3-d]pyrimidin-2(1H)-one (100.00 mg; 0.23 mmol; 1.00 eq.),3-fluorobenzoic acid (35.80 mg; 0.26 mmol; 1.10 eq.), pybop (157.16 mg; 0.30 mmol; 1.30 eq.), DMF (4.00 ml), and N,N-diisopropylethylamine (115.48 μl; 0.70 mmol; 3.00 eq.) was stirred at room temperature for 22 hr. Additional pybop was added and the reaction was heated to 100 degrees C. but the reaction did not go to completion. The reaction was concentrated, redissolved in DMSO, and purified via prep HPLC to afford 17 mg (26%) of 3-fluoro-N-(6-{[3-(4-methoxybenzyl)-2-oxo-1,2,3,4-tetrahydropyrido[2,3-d]pyrimidin-5-yl]oxy}-1-methyl-1H-indazol-3-yl)benzamide as a yellow solid. LC-MS (M+H=553, obsd.=553).
