Reaction Steps

5.54 g of lithium hydroxide·hydrate was added to 24.2 g of 7-acetoxy-4-chloro-5,6-dihydro-7H-cyclopenta[d]pyrimidine dissolved in 150 ml of tetrahydrofuran, and the mixture was stirred at room temperature for about 20 hours. After the reaction, water was added to the reaction mixture, and then the mixture was extracted with chloroform. The extract was dried over anhydrous sodium sulfate and then condensed. The obtained residue was applied to silica gel column chromatography to obtain 10.5 g of 4-chloro-7-hydroxy-5,6-dihydro-7H-cyclopenta[d]pyrimidine.
