Versuchsvorschrift

A mixture of 5.4 g (50 mmol) of 3-chloropropionic acid and 13.1 g (50 mmol) of triphenylphosphine were heated for 2 hours at 145° C. and 2 hours at 95° C. The product, a glassy solid, was dissolved in 200 mL of CHCl3, to which was added 100 mL of Et2O. The volume was reduced to 250 mL. 5 mL of acetone was added to the solution. After 2 hours, 10.98 g of a solid was collected and used immediately in the manner described in Example 29, below.
