Procedure
To a solution of 6-(4-chlorosulfonylphenyl)-3-diazo-2,4-hexanedione (1.0 g, 3.2 mmol) obtained in Example 3, (3) in acetonitrile (5 ml), 28% aqueous ammonia (2 g) was added dropwise at 5°-10° C., and stirring was continued for 6 h at room temperature. Then the mixture was evaporated under reduced pressure and the residue was chromatographed on silica gel (Wako Gel C-200; manufactured by Wako Pure Chemical Industries, Ltd.) with n-hexane/ethyl acetate (from 5:1 to 2:1) as eluent to give the title compound as a white amorphous solid; yield: 800 mg; mp 109.5°-111.5° C.
