Procedure

The material from above benzyl (S)-1-((1S,2R,4R)-2-(tert-butylsulfonylmethyl)-4-(isopropyl(methyl)amino)cyclohexyl)-2-oxopyrrolidin-3-ylcarbamate (1.0 g) was dissolved in 33% HBr/AcOH (5 mL) at rt. The solution was stirred for 30 min before Et2O was added. This resulted in a precipitate which was isolated. The solid was dissolved in EtOAc and was washed with sat. Na2CO3 solution. The organic phase was dried (MgSO4), filtered, and concentrated to afford (S)-3-amino-1-((1S,2R,4R)-2-(tert-butylsulfonylmethyl)-4-(isopropyl(methyl)amino)cyclohexyl)pyrrolidin-2-one (250 mg). MS found: (M+H)+=388.4.
