Reaction Steps

8.99 g of 2-(5-chloro-2-methoxy-4-morpholinophenyl)-propionic acid (0.03 mole) are boiled in 48% hydrogen bromide solution for 2 hours. The reaction mixture is cooled and concentrated and extracted 3 times with methylene chloride. The organic phases are washed neutral, combined, dried over sodium sulphate and concentrated in a vacuum rotary evaporator. In this manner 5-chloro-3-methyl-6-(morpholin-4-yl)-benzofuran-2(3H)-one having a melting point of 103°-105° is obtained.
