실험 절차

Using a procedure analogous to that used to prepare 30A, 4-bromo-2-chloro-1-iodobenzene (8 g, 25 mmol) was reacted with trimethyl(vinyl)silane in a pressure vessel at 160° C. for 1 h and worked up in a manner similar as in 30A to yield 61A (5.2 g, 96%) as an oil. 1H NMR (400 MHz, CDCl3) δ ppm 5.41 (d, J=11.86 Hz, 1 H) 7.02 (dd, J=17.36, 11.21 Hz, 1 H) 7.35 (dd, 1 H) 7.41 (d, 1 H) 7.52 (d, J=1.76 Hz, 1 H).
