Procedure
To a stirred mixture of 17.7 g methyl-trans-3-methoxyacrylate and 32.3 g trimethyl ortho formate was added 1.0 g FeCl3. The mixture was heated to 40° C. for 24 hours, cooled to room temperature and 5.00 g anhydrous sodium carbonate were added. After stirring for 2 hours, the mixture was filtered and the filter-cake washed with trimethyl ortho formate. Fractional distillation gave 12.9 g colorless liquid (76.5% of theoretical based on converted methyl-trans-3-methoxyacrylate) of boiling point 100° C./4 mm Hg. A GC-analysis of the liquid revealed an assay of >99% (FID-detection).
