Procedure

4-[2-(3-Cyano-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazol-8-yloxy)-acetyl]-piperazine-1-carboxylic acid tert-butyl ester (Compound A9-15-1, 20 mg) was added with 4 N hydrochloric acid and dioxane solution (1 ml), and stirred in an water bath at 10° C. for 4 hr. Water was added to the reaction solution and the resulting precipitates were filtered and dried to obtain the title compound (15 mg, white powder).
