Reaction Steps

A mixture of 3-[2-methyl-5-(5-methyl-[1,3,4]oxadiazol-2-yl)-phenoxymethyl]-thieno[3,2-c]pyridine-7-carboxylic acid ethyl ester and 3-[2-methyl-5-(5-methyl-[1,3,4]oxadiazol-2-yl)-phenoxymethyl]-thieno[3,2-c]pyridine-7-carboxylic acid methyl ester (0.08 g, 0.20 mmol) (from Example 36 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 C18 column chromatography eluting with acetonitrile/water to give 3-{5-[4-(2-hydroxy-ethyl)-5-methyl-4H-[1,2,4]triazol-3-yl]-2-methyl-phenoxymethyl}-thieno[3,2-c]pyridine-7-carboxylic acid (2-hydroxy-ethyl)-amide as a white solid. (Yield: 37.0 mg, 39%).
