실험 절차

A solution of 1-(4-methoxybenzyl)-4-(4-amino-5-chloro-2-fluorophenoxy)-N-(1-methylpiperidin-4-yl)-1H-pyrazolo[3,4-b]pyridin-3-amine (130 mg, 0.254 mmol) in CH2Cl2 (1 mL) was added into a solution of 2-(4-fluorophenyl)-3-oxo-2,3-dihydropyridazine-4-carboxylic acid (119 mg, 0.509 mmol, obtained from Example 19 Step C), triethylamine (0.213 ml, 1.53 mmol), EDCI (293 mg, 1.53 mmol) and HOBT (206 mg, 1.53 mmol) in CH2Cl2 (2 mL). The reaction mixture was stirred for 12 hours at ambient temperature. The reaction was diluted with CH2Cl2 and washed with saturated aqueous NaHCO3 and brine. The organic layer obtained was dried with Na2SO4, filtered and concentrated. The residue was purified by flash column chromatography (5% MeOH in CH2Cl2) to afford the product (100 mg, 54.1% yield) as a yellow solid. LRMS (APCI pos) m/e 727.2 (M+H).
