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 (2.92 g, 9.51 mmol) and (S)-3-(tert-butoxycarbonyl(isopropyl)amino)-2-(4-chlorophenyl)propanoic acid (3.25 g, 9.51 mmol) in DCM (40 mL) and DIEA (5.0 mL, 28.7 mmol) was stirred at room temperature for 10 minutes. HBTU (3.61 g, 9.51 mmol) was added to the mixture. The mixture was stirred at room temperature for 1 hour. The solvent was removed, and the residue was dissolved in ethyl acetate (500 mL) and washed with water (6×100 mL). The organic phase was dried and concentrated. The residue was subject to column chromatography, eluted by EtOAc-DCM/MeOH (20:1) to give tert-butyl (S)-2-(4-chlorophenyl)-3-(4-((5R,7R)-7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)-3-oxopropyl(isopropyl)carbamate (3.68 g, 69%.) LC/MS (APCI+) m/z 558.2 [M+H]+.
