Reaction Steps

(6aR,9aS)-5,6a,7,8,9,9a-hexahydro-5-methyl-3-(methylthio)-2-(4-(6-fluoropyridin-2-yl)benzyl)-cyclopent[4,5]imidazo[1,2-a]pyrazolo[4,3-e]pyrimidin-4(2H)-one (35.2 mg, 0.076 mmol) is dissolved in CH3CN (0.5 mL) and CH3OH (2 mL), and then an aqueous solution of oxone (93.7 mg, 0.152 mmol) is added. The reaction mixture is stirred at room temperature for 20 h, and then purified by a semi-preparative HPLC to give pure product as white solids. MS (ESI) m/z 479.2 [M+H]+.
