Procedure

Reaction of styrene with Grubbs' second generation catalyst for 19 hours gave the title compound in 94% yield. The 1H and 13C NMR spectra agreed with those reported in the literature. 1H NMR (CDCl3): 7.11 (s, 2H), 7.25 (tt, 2H, J=7.2, 1.2 Hz), 7.34 (m, 4H), 7.50 (m, 413C NMR (CDCl3): 126.51, 127.62, 128.65, 128.68, 137.28.
