Versuchsvorschrift

(R)-(4-(4-chlorophthalazin-1-yl)-3-methylpiperazin-1-yl)(phenyl)methanone (JK-5) (200 mg, 0.545 mmol), 4-(2-(tetrahydro-2H-pyran-2-yloxy)ethyl)phenylboronic acid (136 mg, 0.545 mmol) and tetrakis(triphenylphosphine)palladium (0) (31.5 mg, 0.0273 mmol) were dissolved in toluene (4 mL) and aqueous sodium carbonate (2.0M, 0.400 mL) under an atmosphere of argon. The reaction was heated at 100° C. for 15 hours, cooled to rt, and taken up in ethyl acetate (80 mL). After washing with aqueous K2CO3 (10%), water, and saturated sodium chloride, the organics were dried (MgSO4) and evaporated to give a yellow oil. Chromatography over silica gel with a gradient of hexanes/0-100% ethyl acetate gave a pale yellow solid, compound 83. MS (M+H)+=537.4.
