Procedure

A solution of 4-amino-3-[3-(2-methyl-2H-tetrazol-5-yl)-phenoxymethyl]-thieno[3,2-c]pyridine-7-carboxylic acid ethyl ester (0.050 g, 0.12 mmol) (from Example 32 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, washed with methanol and dried to give 4-amino-3-[3-(2-methyl-2H-tetrazol-5-yl)-phenoxymethyl]-thieno[3,2-c]pyridine-7-carboxylic acid (2-hydroxy-ethyl)-amide as a white powder. (Yield 39.0 mg, 75%).
