実験手順

A solution of the compound 22 (690 mg, 2 mmol) and p-toluenesulfonic acid hydrate (400 mg, 2.1 mmol) in a mixture of tetrahydrofuran (10 mL) - toluene (100 ML) was concentrated under reduced pressure. The residue was dried on an oil bath at 55° C. for 40 minutes. The residue was dissolved in toluene (100 mL), and 1-methoxycyclooctene (1.84 g, 10 mmol) was added thereto. The reaction mixture was heated with reflux over 1 hours and concentrated to a small quantity. After cooling down at room temperature, triethylamine (0.4 mL) was added thereto. The reaction mixture was purified by chromatography on an alumina column (eluate: hexane - ethyl acetate (15:1)) to give the compound 47 (790 mg, 87%). Mp 73-74° C. PMR (CDCl3 -0.1% d5 -Py): δH1.24 (6 H, d, J 4.6 Hz, (CH3)2C), 3.13 (2 H, t, J 4.2 Hz, CH2 -Im), 3.08 (1 H, m, (CH3)2CH), 3.51 (3 H, 8, NCH3), 3.96 (2 H, t, J 4.2 Hz, OCH2), 4.51(1 H, t, J 5.6 Hz, =CH), 6.77 (2 H, d, J 2 Hz, arom-H), 7.09 (1 H, t-like, arom-H).
