Versuchsvorschrift

Compound D (50 mg, 0.13 mmol, 1.0 eq), 5-ethynyl-2-methyl-pyrimidine (30 mg, 0.26 mmol, 2.0 eq), copper(I) iodide (2.5 mg, 0.013 mmol, 0.010 eq), bis(triphenylphosphine)palladium(II) dichloride (4.5 mg, 0.0064 mmol, 0.050 eq) and triethylamine (53.6 μL, 0.38 mmol, 3.0 eq) were dissolved in DMF (1.3 mL) in a microwave vial and heated in a microwave reactor at 150° C. for 15 minutes. The reaction was purified directly using reverse phase chromatography to afford 30 mg (55%) of the title compound as white solid. 1H NMR (400 MHz, DMSO-d6) δ 8.93 (s, 2H), 8.47 (s, 1H), 8.40 (d, J=2.0 Hz, 1H), 7.81-7.76 (m, 3H), 7.53 (t, J=8.7 Hz, 2H), 7.02 (d, J=8.80 Hz, 1H), 4.21 (q, J=7.1 Hz, 2H), 2.66 (s, 3H), 1.25 (t, J=7.1 Hz, 3H); ES-MS [M+1]+: 428.2.
