実験手順
Using a procedure analogous to that used to prepare 30A, 5-bromo-2-iodo-1,3-dimethylbenzene (15.6 g, 48 mmol) was reacted with trimethyl(vinyl)silane in a pressure vessel at 160° C. for 1 h to yield 32A (10.0 g, 94%) as a clear oil. 1H NMR (400 MHz, CDCl3) δ ppm 2.26 (s, 6 H) 5.24 (dd, J=17.86, 1.92 Hz, 1 H) 5.55 (dd, J=11.54, 2.20 Hz, 1 H) 7.18 (s, 2 H).
