실험 절차
A solution of 4-(2,5-dioxo-1-(3-(trifluoromethyl)phenyl)-2,3,4,5,6,7-hexahydro-1H-cyclopenta[d]pyrimidin-4-yl)benzonitrile (example 1, 3.00 g, 7.55 mmol) in dry acetonitrile (45 mL) is cooled in an ice bath and treated dropwise with lithium diisopropylamide (2 M in THF, 7.55 mL, 15.1 mmol), while the temperature is kept below 5° C. Methyl 2-bromoacetate (2.31 g, 15.1 mmol) is added and the mixture is stirred for 1.5 h. The mixture is then warmed to room temperature and stirred at room temperature over night. Water (0.5 mL) is added, the mixture is concentrated, and the residue is purified by reversed phase HPLC (Waters SunFire™-C18, gradient of acetonitrile in water, 0.1% TFA). Yield: 2.64 g; ESI mass spectrum [M+H]+=470; Retention time HPLC: 1.65 min (W018_801).
