Summary 1. 2-Benzyloxy-3, 5-dichlorobenzoic acid, heated for forty minutes at 153', yielded 20% of 3, 5-dichlorosalicylic acid, 65% of benzyl 3, 5-dichlorosalicylate and 10% of carbon dioxide. The same result was obtained in dimethylaniline solution, and in a quartz tube. A slow rearrangement was also observed in refluxing acetic acid solution.
