    Abstract: PURPOSE: A pyrazolopyrimidine derivative as a cyclin-dependent kinase inhibitor and a process for preparing the same are provided. The compound inhibits cyclin-dependent kinase(CDK) regulating cell division cycle and has low toxicity. Therefore, it can be useful for prevention and treatment of liver cancer, breast cancer, stomach cancer, colon cancer or rectal cancer caused by activation of CDK. CONSTITUTION: A pyrazolopyrimidine derivative is represented by the formula(1), wherein R1 comprises ortho, meta, or para substituent, and is bromo, chloro, fluoro, methoxy, hydrogen, nitro or amino; R2 is hydrogen or C3 or less of lower alkyl; R3 is hydrogen or C3 or less of lower alkyl, or hydroxyethyl; and n is an integer of 0 or 1. A method for preparing the pyrazolopyrimidine derivative represented by the formula(1) comprises the steps of: reacting 6-methylmercaptopyrazolopyrimidine of the formula(IV) with meta-chloroperbenzoic acid in the presence of an organic solvent such as chloroform or dichloromethane at -10 to 10 deg. C for 2 to 5 hours and at room temperature for 3 to 12 hours to prepare 6-methylsulfonylpyrazolopyrimidine of the formula(II); and nucleophilic substitution reaction of 6-methylsulfonylpyrazolopyrimidine of the formula(II) with hydroxyethylamine in the presence of a mixed organic solvent of isopropanol or n-butanol and dimethylsulfoxide or dimethylformamide at 70 to 100 deg. C for 1 to 6 hours.
