Reaction Steps

To solution of 4-amino-3-{5-[1-(4-chloro-benzyl)-1H-[1,2,3]triazol-4-yl]-2-methyl-phenoxymethyl}-thieno[3,2-c]pyridine-7-carboxylic acid (2-hydroxy-ethyl)-amide (0.159 g, 0.29 mmol) (from Example 37 supra) in methanol (10 mL) was treated with toluene-4-sulfonic acid hydrate (61.0 mg, 0.319 mmol) and heated at room temperature for 40 minutes. The solution was concentrated. The residue washed with diethyl ether, dissolved in water and lyophilized to 4-amino-3-{5-[1-(4-chloro-benzyl)-1H-[1,2,3]triazol-4-yl]-2-methyl-phenoxymethyl}-thieno[3,2-c]pyridine-7-carboxylic acid (2-hydroxy-ethyl)-amide 1.5 toluene-4-sulfonic acid salt. (Yield 0.21 g, 100%).
