Versuchsvorschrift

0.66 g (7.3 mmoles) of acryloyl chloride was added to a solution of 2 g (14.3 mmoles) of p-aminobenzoic acid in 40 mL tetrahydrofuran (THF). A white precipitate consisting of p-aminobenzoic acid hydrochloride formed. The suspension was filtered and the filtrate was dried by vacuum evaporation to yield 1.1 g p-acrylamidobenzoic acid (reaction shown in FIG. 16a).
