At 0° C., 68 mg of m-chloroperbenzoic acid was added to a chloroform solution of 91 mg of 2-(2-methoxyphenyl)-1-methyl-6-(methylthio)-1,2-dihydro-3H-pyrazolo[3,4-d]pyrimidin-3-one, and stirred for 1 hour. Aqueous saturated sodium hydrogencarbonate solution was added thereto, and extracted with chloroform to obtain crude 2-(2-methoxyphenyl)-1-methyl-6-(methylsulfinyl)-1,2-dihydro-3H-pyrazolo[3,4-d]pyrimidin-3-one.
