実験手順

Compound 7 (1.80 g, 6.0 mmol), 1.14 g (6.0 mmol) of toluene-4-sulfonic acid (CH3C6H4SO3H.H2O), and 35 mL of 2-butyloctanol were added into a 250 mL 3-neck flask equipped with a ondenser. The system was heated at 180° C. overnight under argon before the mixture was cooled down to room temperature. Hexane (200 mL) was added and the organic layer was washed with saturated NaHCO3 before the solvent was removed under vacuum. Excess 2-butyloctanol was distilled out under vacuum. Column chromatography (silica gel) with an eluent of hexane/dichloromethane (v/v, 100/4) yielded product BB-4 as a colorless liquid (2.5 g, ˜68.5% yield). 1H NMR (CDCl3, 500 MHz): δ 7.96 (d, 2H, J=5.5 Hz), δ 7.60 (d, 2H, J=5.5 Hz), δ 7.50 (s, 2H), δ 4.23 (d, 4H, J=5.5 Hz), δ 1.99 (m, 2H), δ 1.33 (m, 32H), δ 0.96 (t, 6H, J=7.0 Hz), δ 0.90 (t, 6H, J=7.0 Hz).
