Participants

Reaction Steps

A microwave vial was charged with 3-fluoro-4-methylphenylboronic acid (0.058 g, 0.38 mmol), 4-chloro-N-(4-(2-(trimethylsilyl)furo[3,2-b]pyridin-7-ylthio)phenyl)phthalazin-1-amine (0.090 g, 0.19 mmol), and sodium carbonate (2.0 M in H2O) (0.38 ml, 0.75 mmol) and dissolved in toluene (1.5 mL) and water (0.2 mL). Pd(Ph3P)4(0.011 g, 0.0094 mmol) was added and the reaction was microwaved at 200° C. for 30 minutes. The reaction was partitioned between water and DCM. The layers were separated and the aqueous layer was extracted twice with DCM. The combined organic layers were dried with sodium sulfate, filtered, and concentrated. The material was redissolved in 2 mL THF and TBAF (0.23 ml, 0.23 mmol) was added. The reaction was stirred at RT overnight. The reaction was concentrated and purified via Gilson HPLC (10-90% ACN:H2O). The clean fractions were partitioned between saturated sodium bicarbonate solution and DCM and the aqueous layer was extracted with DCM. The combined organic layers were dried with sodium sulfate, filtered, and concentrated to afford 4-(3-fluoro-4-methylphenyl)-N-(4-(furo[3,2-b]pyridin-7-ylthio)phenyl)phthalazin-1-amine as a light yellow solid. MS: M+H+=479.1
