a Ethyl 5-chloro-2-methoxycinnamate A solution of 10.6 g (48.2 mmol) of 2-bromo-4-chloroanisole in 30 ml of triethylamine was treated with 1 0.1 ml (81.2 mmol) of ethyl acrylate, 1.23 g of tri-o-tolylphosphine, and 0.45 g of palladium(II) acetate in an argon atmosphere. The reaction mixture was stirred at 100 C. for 2 days, then diluted with EA and filtered through Celite. The filtrate was washed with 1 N HCl and saturated NaCl solution, dried over Na2SO4, and concentrated. After chromatographic purification over SiO2 using EA/heptane (1:8) as an eluent, 0.85 g of the title compound resulted as a pale yellow oil. Rf (SiO2, EA/heptane 1:4)=0.34. MS (ESI): m/e=241 (M+H)+
