The procedure described in Example 1 is followed, except that 17.1 g (0.1 mol) of 2-methoxybenzoyl chloride, 13 g (0.125 mol) of styrene, 23.2 g (0.125 mol) of tri-n-butylamine and 0.225 g (0.001 mol) of palladium acetate are used. After a reaction time of 3 hours at a bath temperature of 140° C., in 100 ml of diethyl carbonate as the solvent, 10.3 g (0.049 mol) of 2-methoxystilbene, corresponding to a yield of 49% of theory, are obtained; melting point 69°-70° C.
