A solution of 4-amino-3-[3-(5-methyl-[1,3,4]oxadiazol-2-yl)-phenoxymethyl]-thieno[3,2-c]pyridine-7-carboxylic acid ethyl ester (0.05 g, 0.12 mmol) (from Example 9 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 reaction mixture was purified by reverse-phase chromatography (C18 column) eluting with acetonitrile-water to give 4-amino-3-[3-(5-methyl-[1,3,4]oxadiazol-2-yl)-phenoxymethyl]-thieno[3,2-c]pyridine-7-carboxylic acid (2-hydroxy-ethyl)-amide as a white powder. (Yield 15.0 mg, 29%).
