실험 절차

A solution containing 300 mg (0.707 mmol) of compound 3-[3-(2,4-dichlorophenyl)-1,9-dimethyl-2-oxo-2,9-dihydro-1H-pyrido[2,3-b]indol-6-yl]-3-oxopropionitrile from Example 20A, 238 mg (2.9 mmol) of sodium acetate and 152 mg (2.2 mmol) of hydroxylamide hydrochloride in 4 ml of CH2Cl2 and 4 ml of MeOH is stirred at 50° C. for 24 h and then at ambient temperature for 18 h. The reaction medium is concentrated by adsorbing it onto silica, and purification is carried out on a silica column, elution being carried out with EtOAc/20% cyclohexane and then 100% EtOAc.
