Procedure
The starting material is prepared as follows: The mixture of 17 g of 2-(5-chloro-2-o-tolylphenyl)-4,4-dimethyl-2-oxazoline (prepared as shown in Example 2), 150 ml of p-dioxane, and 160 ml of 5 N aqueous hydrochloric acid is refluxed for 3 days while stirring. It is evaporated, the residue taken up in diethyl ether, the organic phase separated, dried, evaporated and the residue crystallized from hexane to yield the 3-chloro-6-o-tolylbenzoic acid melting at 135°-137°.
