methyl 4H-thieno[3,2-b]pyrrole-5-carboxylate → 4-(7-fluoro-naphthalen-1-ylmethyl)-4H-thieno[3,2-b]pyrrole-5-carboxylic acid methyl ester

Participants

Reaction Steps

Using general procedure B, methyl 4H-thieno[3,2-b]pyrrole-5-carboxylate was coupled with 1-bromomethyl-7-fluoro-naphthalene (from Example 49.3.) to give 4-(7-fluoro-naphthalen-1-ylmethyl)-4H-thieno[3,2-b]pyrrole-5-carboxylic acid methyl ester which was hydrolyzed as described in the general procedure B (Exp. 2.2) to give the title compound as a white solid. MS: 324.4 ([M−H]−).
