Procedure
5-Fluoro-3-methylaminomethyl-1-naphthalen-1-ylmethyl-1H-indole-2-carboxylic acid ethyl ester (from Example 86.1.) was reacted with ethyl chloroformate as described in Example 77.1. to give 3-[(ethoxycarbonyl-methyl-amino)-methyl]-5-fluoro-1-naphthalen-1-ylmethyl-1H-indole-2-carboxylic acid ethyl ester which was hydrolyzed as described in the general procedure B (Exp. 2.2) to give the title compound as a colorless solid. MS: 433.5 ([M−H]−).
