Procedure

The title compound was prepared as follows: To a solution of 250 mg of [(1-chloro-4-hydroxy-isoquinoline-3-carbonyl)-amino]-acetic acid, (U.S. Pat. No. 6,093,730, disclosed as N-((1-chloro-4-hydroxyisoquinoline-3-yl)carbonyl)glycine), in 1 ml 1-methyl-2-pyrrolidinone was added 1.2 ml of benzenethiol. The solution was heated at 130 to 150° C. in a sealed tube for 16 h. The solution was concentrated under vacuum. The resultant residue was crystallized from methanol to yield 91 mg of a tan solid; MS (−) m/z 353.07 (M−1)
