Versuchsvorschrift

A suspension of 3-[3-(3-chloro-benzoylamino)-phenoxymethyl]-thieno[3,2-c]pyridine-7-carboxylic acid ethyl ester (34.0 mg, 0.073 mmol) (from Example 10 supra) in methyl sulfoxide (1 mL) and ethanolamine (3 mL) (Aldrich) was heated at 135° C. for 2 hours in a microwave reactor. The solvent was removed in vacuum and the residue was treated with MeOH (2 mL). The resulting white precipitate was filtered, washed with cold MeOH and dried to give 3-[3-(3-chloro-benzoylamino)-phenoxymethyl]-thieno[3,2-c]pyridine-7-carboxylic acid (2-hydroxy-ethyl)-amide as a white solid. (Yield 25.7 mg, 73%).
