Reaction Steps

4-{4-[4-(2-Chloro-4-nitroimidazol-1-yl)-2-hydroxy-2-methylbutoxy]phenyl}piperazine-1-carboxylic acid tert-butyl ester (2.12 g) was dissolved in dimethylformamide (21 ml). 60% sodium hydride (0.24 g) was added thereto, and the mixture was stirred at room temperature for 3 hours. Water was added to the reaction mixture, the mixture was subjected to extraction with methylene chloride, and then dried over sodium sulfate. After filtering, the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (methylene chloride:ethyl acetate=1:0→methylene chloride:ethyl acetate=1:1) to afford the title compound as a colorless powder (1.05 g).
