Participants

Reaction Steps

To a stirred solution of (S)-methyl 2-((tert-butoxycarbonyl)(4-(2-(3-cyano-4-isopropoxyphenyl)thiazol-5-yl)-2,3-dihydro-1H-inden-1-yl)amino)acetate (120 mg, 0.22 mmol) in MeOH (2 mL) was added 6N sodium hydroxide (180 μL) and the mixture was stirred at room temperature for overnight. The solvent was evaporated and the residue was dissolved in water (5 mL) and acidified with 1N HCl. The mixture was extracted with EA (3×5 mL) and the organic layers washed with brine, dried over MgSO4, and concentrated to afford 110 mg (94%) of (S)-2-((tert-butoxycarbonyl)(4-(2-(3-cyano-4-isopropoxyphenyl)thiazol-5-yl)-2,3-dihydro-1H-inden-1-yl)amino)acetic acid as white solid which was used in the next experiments without purification. LCMS-ESI (m/z) calculated for C29H31N3O5S: 533.2; found 534.2 [M+H]+, tR=3.92 min.
