실험 절차

DIPEA (35.5 mg, 0.275 mmol) was added to a suspension of (R)-5-methyl-4-(piperazin-1-yl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine dihydrochloride (20 mg, 0.69 mmol), 3-(tert-butoxycarbonyl(isopropyl)amino)-2-(4-chlorophenyl)-2-hydroxypropanoic acid (29.5 mg, 0.082 mmol), and O-(1H-Benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (31.3 mg, 0.082 mmol) in CH2Cl2 (5.0 mL) at room temperature. The resulting mixture was stirred overnight, diluted with EtOAc, washed with saturated aqueous. NaHCO3 and saturated aqueous NH4Cl. The organic layer was dried (MgSO4) and concentrated. The residue was purified by a silica cartridge (5.0 g) and eluted by a mixture of EtOAc and hexane (60:40) to give tert-butyl 2-(4-chlorophenyl)-2-hydroxy-3-(4-((R)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)piperazin-1-yl)-3-oxopropyl(isopropyl)carbamate as a clear oil (27 mg, 70%). LCMS (APCI+) [M-Boc+H]+ 558.1; Rf: 4.41 min.
