Participants

Reaction Steps

1-(5-Fluoro-benzo[b]thiophen-3-ylmethyl)-3-formyl-1H-indole-2-carboxylic acid ethyl ester (from Example 115.1.) was converted to 1-(5-fluoro-benzo[b]thiophen-3-ylmethyl)-3-methylaminomethyl-1H-indole-2-carboxylic acid ethyl ester as described in Example 86.1. 117.2. 1-(5-fluoro-benzo[b]thiophen-3-ylmethyl)-3-methylaminomethyl-1H-indole-2-carboxylic acid ethyl ester was converted to 1-(5-fluoro-benzo[b]thiophen-3-ylmethyl)-3-[(methoxycarbonyl-methyl-amino)-methyl]-1H-indole-2-carboxylic acid ethyl ester as described in Example 77.1. which was hydrolyzed as described in the general procedure B (Exp. 2.2) to give 1-(5-fluoro-benzo[b]thiophen-3-ylmethyl)-3-[(methoxycarbonyl-methyl-amino)-methyl]-1H-indole-2-carboxylic acid as a white solid. MS: 425.5 ([M−H]−).
