1-Ethylisoquinoline and N-hydroxymethyl dichloroacetamide were reacted in the same way as in step (b) of Example 18 to afford 1-ethyl-5-dichloroacetylaminomethylisoquinoline. The product was reacted successively in the same way as in steps (c), (d), (e) and (f) of Example 18 to afford 1-ethylisoquinoline-5-acetonitrile. The product was treated in the same way as in Example 3 to afford 1-ethylisoquinoline-5-acetic acid having a melting point of 166.2° to 180.8° C.
