실험 절차

DIPEA (0.089 mL, 0.51 mmol) was added to a stirred suspension of (S)-5-methyl-4-(piperazin-1-yl)-5,7-dihydrothieno[3,4-d]pyrimidine dihydrochloride (40 mg, 0.13 mmol), 3-(tert-butoxycarbonyl(isopropyl)amino)-2-(4-fluorophenyl)propanoic acid (50 mg, 0.15 mmol) and O-(1H-Benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (58 mg, 0.15 mmol) in DCM (10 mL) at room temperature. The reaction mixture was stirred at room temperature for 4 hours, diluted with EtOAc, washed with saturated aqueous bicarbonate and then 1N HCl. The combined organic layers were dried over Na2SO4 and concentrated in vacuo. The residue was purified by silica gel chromatography (75% EtOAc/hexanes) to give tert-butyl 2-(4-fluorophenyl)-3-(4-((S)-5-methyl-5,7-dihydrothieno[3,4-d]pyrimidin-4-yl)piperazin-1-yl)-3-oxopropyl(isopropyl)carbamate (50 mg, 72% yield) as a mixture of 2 diastereomers. LCMS (APCI+) [M-Boc+H]+ 444.
