Versuchsvorschrift

A mixture of Example 21A (150 mg, 0.48 mmol), (2-propynyloxy)benzene (0.13 mL, 0.96 mmol), PdCl2(PPh3)2 (17 mg, 0.024 mmol), PPh3 (15 mg, 0.057 mmol), CuI (3 mg), and Et3N (1 mL, 7.2 mmol) in DME/water/ethanol (70:30:20 mixture, 2 mL) was heated in a sealed vial to 125° C. for 25 minutes with stirring in a Smith Synthesizer microwave oven (at 300 W). The reaction mixture was concentrated and the residue was purified by HPLC using the conditions described in Example 21C to provide 47 mg (27% yield) of the desired product. 1H NMR (400 MHz, DMSO-d6) δ 2.71 (d, J=4.6 Hz, 3H), 5.18 (s, 2H), 6.50 (d, J=16.0 Hz, 1H), 6.91 (s, 2H), 7.00 (t, J=7.4 Hz, 1H), 7.08 (dd, J=8.8, 0.9 Hz, 2H), 7.35 (dd, J=8.8, 7.4 Hz, 2H), 7.52 (d, J=16.0 Hz, 1H), 8.10-8.13 (m, 2H), 8.14 (s, 1H); MS (ESI(+)) m/e 364.0 (M+H)+.
