実験手順

A mixture of the product of Example 18A (2.33 g, 14.3 mmol), tert-butylchlorodimethylsilane (2.6 g, 17.2 mmol), and imidazole (2.9 g, 42.3 mmol) was stirred in 40 mL of dichloromethane at rt overnight. The mixture was then washed several times with water and once with brine. Drying over Na2SO4, filtered and evaporation afforded the product as a dark purple oil, 2.6 g (65%). 1H NMR (DMSO-d6) δ 6.77 (dd, J=7.8, 7.4 Hz, 1H), 6.42 (d, J=7.8 Hz, 1H), 6.28 (d, J=7.4 Hz, 1H), 4.7 (br s, 2H), 4.11 (m, 1H), 2.75 (m, 3H), 2.24 (m, 1H), 1.82 (m, 1H), 1.63 (m, 1H), 0.88 (s, 9H), 0.09 (s, 6H); MS (ESI+) m/z 278 (M+H)+.
