3 g (19.9 mmol) of 4-aminomethylbenzoic acid was suspended in 100 ml of ethanol. 10 ml of ethanol containing 25% of hydrogen chloride was added to the suspension, and they were heated under reflux for 8 hours. The solvent was evaporated, and the title compound was obtained by the same isolation process as that of step 1 in Example 1 with ethyl acetate as the extractant.
