Reaction Steps

A mixture comprising tert-butyl 1-((2R)-1-(4-(4-fluorophenyl)-2-methyl-1-oxo-2,7-diazaspiro[4.5]decan-7-yl)-3-(1H-indol-3-yl)-1-oxopropan-2-ylamino)-2-methyl-1-oxopropan-2-ylcarbamate (312.3 mg, 0.493 mmol) (step 1) and TFA (0.380 ml, 4.93 mmol) in DCM (3 ml) was stirred at room temperature for 17 hours. TFA (1 mL, 13 mmol) was added to the reaction mixture. After 3 h 45 min 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.
