Procedure

To a methanol suspension of 180 mg of 6-(2-acetoxyethyl)-7-hydroxy-3-(4-phenylthiophenyl)pyrazolo[1,5-a]pyrimidine, 2 ml of 2N sodium hydroxide was added, and stirred for 21 hours at room temperature. Turning acidic with 10% hydrochloric acid, the precipitate was filtered, washed with-water, dried, and the title compound was obtained (150 mg, 93%).
