Reaction Steps

The title compound was prepared as follows: 50 mg of [(4-hydroxy-1-phenylsulfanyl-isoquinoline-3-carbonyl)-amino]-acetic acid, Example D-110, was dissolved in 0.3 ml 1-methyl-2-pyrolydinone and 0.7 ml dichloromethane. The solution was cooled to 0° C. and 26 mg of 75% 3-chloroperoxybenzoic acid was added. The solution was stirred for 2 hours at room temperature, then concentrated under hign vacuum. The resultant residue was triturated with ethyl acetate to provide 32 mg of the product as a white solid; MS (−) m/z 369.08 (M−1)
