Procedure

5-Amino-4-(p-methoxyphenoxy)-3-mercaptobenzoic acid (2 g) is dissolved in 1 N sodium hydrogen carbonate (50 ml), and after addition of benzyl bromide (0.85 ml), the reaction mixture is stirred for 17 hours. After extraction twice with diethyl ether (25 ml), the aqueous layer is adjusted to pH 2 by addition of 4 N hydrochloric acid. The precipitated 5-amino-3-benzylthio-4-(p-methoxyphenoxy)-benzoic acid is collected and recrystallized from aqueous ethanol. After drying in vacuo at 80°C, the compound is obtained with a melting point of 158°-161°C.
