실험 절차

A mixture comprising tert-butyl 1-((2R)-1-(4-(4-fluorophenyl)-2-isopropyl-1-oxo-2,7-diazaspiro[4.5]decan-7-yl)-3-(1-methyl-1H-indol-3-yl)-1-oxopropan-2-ylamino)-2-methyl-1-oxopropan-2-ylcarbamate (378 mg, 0.559 mmol) (step 1) and TFA (0.431 ml, 5.59 mmol) in DCM (3 ml) was stirred at room temperature for 4 hours. The solvent was removed in vacuo to afford a colourless oil. The oil was dissolved with methanol (3 ml) and passed through a 10 g SCX-2 cartridge eluting with 2M NH3 in methanol (70 ml). The solvent was removed in vacuo to yield the title compound as diastereomeric mixture.
