Using a procedure analogous to that used to prepare 30A, 4-bromo-2-ethyl-1-iodobenzene (2.1 g, 6.9 mmol) was reacted with trimethyl(vinyl)silane in a pressure vessel at 175° C. for 45 min to yield 36A (1.1 g, 77%) as a clear oil. 1H NMR (400 MHz, CDCl3) δ ppm 1.03 (t, J=7.58 Hz, 3 H) 2.51 (q, J=7.66 Hz, 2 H) 5.15 (dd, J=10.99, 1.14 Hz, 1 H) 5.47 (dd, J=17.31, 1.14 Hz, 1 H) 6.74 (dd, J=17.43, 11.12 Hz, 1 H) 7.08-7.20 (m, 3 H).
