Versuchsvorschrift

To a solution of Example 57b (0.500 g, 0.981 mmoles) in THF (14 ml), 2-Methyl-3-butyn-2-ol (0.1 ml, 1.178 mmoles) diisopropylamine (0.70 ml, 4.90 mmoles), copper(I) iodide (18.6 mg, 0.098 mmoles) and) Tetrakistriphenylphosphine Palladium (0.113 g, 0.098 mmoles) were added and the system is degassed for 30 min. and heated to reflux for 4 h. The reaction mixture filtered through celite pad and washed with ethyl acetate. The filtrate was dried over sodium sulphate and concentrated under reduced pressure. The crude product was purified by column chromatography with methanol: dichloromethane to afford the title compound as brown solid (0.311 g, 68% yield). MP: 109-113° C. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): δ 8.05(m,3H), 7.83(dt, J=8.6, 1.5 Hz, 1H), 7.61(d, J=8.4 Hz, 1H), 7.52(t, J=7.2 Hz, 1H), 7.30-7.11(m, 4H), 5.84(q, J=7.1z, 1H)5.74(s,1H), 1.82(d, J=7.0 Hz, 3H),1.46(s,6H). Mass: 466.09(M++1).
