Reaction Steps

The reaction was conducted according to the General Procedure by heating benzofuran (59 mg, 0.5 mmol, 1 equiv.), KOt-Bu (19.6 mg, 0.18 mmol, 0.35 equiv.) and Et3SiH (239 microliters, 1.5 mmol, 3 equiv.) in 1 mL of tetrahydrofuran for 45 hours at 60° C. After aqueous work up, the crude reaction mixture was purified by chromatography on silica eluting with hexanes (isochratic) to obtain 44 mg (38%) of the title compound as a colourless oil. 1H NMR (500 MHz, Acetone-d6) δ 7.64 (ddd, J=7.7, 1.3, 0.7 Hz, 1H), 7.53 (dd, J=8.2, 0.9 Hz, 1H), 7.30 (ddd, J=8.3, 7.2, 1.3 Hz, 1H), 7.22 (ddd, J=7.7, 7.2, 1.0 Hz, 1H), 7.16 (d, J=1.0 Hz, 1H), 1.09-0.98 (m, 9H), 0.92-0.84 (m, 6H).
