Procedure

Methyl 4-[(6-chloro-2-naphthyl)sulfonyl)-1-[methyl[1-(4-pyridinyl)-4-piperidinyl]amino]-6-oxo-2-piperazinecarboxylate hydrochloride (0.3 g) obtained in Example 54 and 13% ammonia/methanol solution (3.5 ml) were heated in a sealed tube at 90° C. for 2 days. The reaction system was cooled, and concentrated under reduced pressure. The residue was purified on a CHP-20 column (water→1% 1N hydrochloric acid-containing 30% aqueous solution of acetonitrile) to obtain the title compound (0.11 g) as a colorless powder.
