Reaction Steps

A suspension of p-chlorobenzimidoethyl ether hydrochloride (16.5 g.) and 3-amino- 4-hydroxyphenylacetic acid (12.53 g.) in methanol (75 ml.) was refluxed for 2 hours. After standing at room temperature overnight the white solid product was removed by filtration. Re-crystallisation from ethanol gave the required acid, m.p. 241°- 242°C.
