Reaction Steps

Iodination of 5-methyl-thiophene-2-carboxylic acid (4-methoxy-benzothiazol-2-yl)-amide (5.17 g, 17 mmol) with iodine monochloride (2.26 ml, 44 mmol), sodium acetate (3.63 g, 44 mmol) and acetic acid (200 ml) in the same manner as described for (4-methoxy-benzothiazol-2-yl)-carbamic acid methyl ester affords the product as off-white solid in 93% yield. MS: m/e=430 (M+).
