実験手順

(6aR,9aS)-5,6a,7,8,9,9a-hexahydro-5-methyl-2-(4-(6-fluoropyridin-2-yl)benzyl)-cyclopent[4,5]imidazo[1,2-a]pyrrolo[4,3-e]pyrimidin-4(2H)-one (38 mg, 0.082 mmol) is dissolved in a mixture of CCl4 and DMF (8/1, v/v). The solution is cooled to 0° C., and then a solution of N-chlorosuccinimide (10.9 mg, 0.082 mmol) in CCl4 and DMF (8/1, v/v) is added dropwise. The reaction mixture is stirred at room temperature for half an hour. Solvents are removed under vacuum, and the residue is purified by a semi-preparative HPLC to give pure product as off white solids (16.5 mg, yield 45%). MS (ESI) m/z 450.1 [M+H]+.
