実験手順

A solution of (5R,7R)-5-methyl-4-(piperazin-1-yl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-7-ol dihydrochloride (30 mg, 98 umol) and potassium 2-(4-chlorophenyl)-3-(2,2,2-trifluoroethylamino)propanoate (31.2 mg, 98 umol) in DMF (1.0 mL) was treated with DIEA (36 uL, 205 umol) and HBTU (41 mg, 107 umol), respectively, at room temperature. The mixture was allowed to stir for 18 hours to completion, and the solution was partitioned between ethyl acetate and water. The aqueous portion was extracted twice, and the organics were combined. The organic portion was washed with water (3×), then brine, separated, dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified by chromatography (silica gel eluted with 9:1 ethyl acetate:MeOH) to afford the pure free-base as a colorless oil. This material was dissolved in ether (1.0 mL), then treated with excess 2.0M HCl in ether. The suspension was concentrated in vacuo to afford the pure 2-(4-chlorophenyl)-1-(4-((5R,7R)-7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)-3-(2,2,2-trifluoroethylamino)propan-1-one dihydrochloride (31 mg, 99%) as a white solid. LCMS (APCI+) m/z 498.2 [M+H]+.
