Reaction Steps

This compounds was synthesised in the same manner as described above. 2-Bromophenylacetic acid (5 g, 23.3 mmol), 4-chlororesorcinol (3.36 g, 23.3 mmol), boron trifloride etherate (20 ml). After standing for two hours a brown precipitate formed (7.4 g, 93.3%); Rf 0.4 hexane/ethyl acetate (70/30). This was shown to be the required product.
