Versuchsvorschrift

A solution of 4-aminobenzoic acid (1.40 g, 10 mmol) in DMF (10 mL) and pyridine (0.5 ml) was cooled to 0° C. To this solution was added of acryloyl chloride (0.94 g, 10 mmol) and the resulting mixture was stirred for 3 hours. The mixture was poured into 200 ml of water and the white solid obtained was filtered, washed with water and ether. Drying under high vacuum provided 1.8 g of the desired product which was used in the next step without purification.
