実験手順
A solution of 4-amino-3-{3-[2-(4-methoxy-benzyl)-2H-tetrazol-5-yl]-phenoxymethyl}-thieno[3,2-c]pyridine-7-carboxylic acid ethyl ester (0.050 g, 0.10 mmol) (from Example 28 supra) in dimethylsulfoxide (0.5 mL) was treated with ethanolamine (1.5 mL) (Aldrich) and heated at 160° C. for 2 hours in a microwave reactor. The precipitate was filtered and dried to give 4-amino-3-{3-[2-(4-methoxy-benzyl)-2H-tetrazol-5-yl]-phenoxymethyl}-thieno[3,2-c]pyridine-7-carboxylic acid (2-hydroxy-ethyl)-amide. (Yield 18.0 mg, 35%).
