実験手順

To a solution of (R)-7,7-difluoro-5-methyl-4-(piperazin-1-yl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine dihydrochloride (0.015 g, 0.046 mmol), (S)-3-(tert-butoxycarbonyl(isopropyl)amino)-2-(4-chlorophenyl)propanoic acid (0.016 g, 0.046 mmol), and DIEA (0.024 ml, 0.14 mmol) in 1.7 mL DCM was added HBTU (0.017 g, 0.046 mmol). The reaction mixture was stirred 15 hours, after which 2M Na2CO3 was added. The mixture was extracted with DCM, and the combined extracts were dried (Na2SO4), filtered, and concentrated in vacuo. The crude was purified on silica gel (Biotage 12S) by first flushing with about 120 mL 5:1 DCM:EA, then gradient to 1:1 DCM:EA to give tert-butyl (S)-2-(4-chlorophenyl)-3-(4-((R)-7,7-difluoro-5-methyl-6,7-dihydro-5H-cyclopenta[d]-pyrimidin-4-yl)piperazin-1-yl)-3-oxopropyl(isopropyl)carbamate (0.018 g, 68% yield) as a white foam. MS (APCI)+ m/z 578 [M+H]+.
