Reaction Steps

2-thienyl acrylic acid was prepared by reaction of 2-thiophene carboxaldehyde with malonic acid. A solution of 2-thiophene carboxaldehyde (25.7 g.), malonic acid (41.6 g.), pyridine (100 ml.), and piperidine (2 ml.) was refluxed for 31/2 hours. 2-thienyl acrylic acid was recovered from the reaction mixture in a manner parallel to that described in Example 41.
