Reaction Steps
A method similar to Example 1 was used and 7.9 g (50 mmol) of monoethyl cyclopropane-1,1-dicarboxylate (prepared according to Example 5a) were converted with 2.8 g (50 mmol) of potassium hydroxide into the potassium salt of monomethyl cyclopropane-1,1-dicarboxylate, and said salt was then reacted with 10 g (35 mmol) of methyl alpha-[2-(bromomethyl)-phenyl]-beta-methoxyacrylate. The product was purified by distillation. Yield: 66%; bp.: 220° C. at 0.3 mbar; colorless oil.
