実験手順

To a solution of ethyl 4-((1S,2S)-2-hydroxycyclopentylamino)-2-(methylthio)pyrimidine-5-carboxylate (1.3 g, 4.37 mmol) in ethanol (15 mL) was added aqueous sodium hydroxide solution (15 mL, 2 N), and the mixture was stirred for 1 h at room temperature. When the starting material was consumed, the reaction mixture was neutralized with saturated aqueous citric acid solution. The solids were collected by filtration and dried to give 4-((1S,2S)-2-hydroxycyclopentylamino)-2-(methylthio)pyrimidine-5-carboxylic acid (1.0 g, 3.7 mmol, yield 85%) as a white solid. MS (ESI): m/z 270.6 [M+1]+.
