Procedure

A solution of benzyl (S)-1-((1S,2R,4R)-2-(1-hydroxypropyl)-4-(isopropyl(methyl)amino)cyclohexyl)-2-oxopyrrolidin-3-ylcarbamate (267 mg) in MeOH (15 mL) was charged with 10% Pd/C, Degussa (˜100 mg). The reaction flask was evacuated and then back-filled with hydrogen; this was repeated two more times. The reaction was stirred under 60 psi of H2 for 4 h and then filtered and concentrated in vacuo to afford the desired (S)-3-amino-1-((1S,2R,4R)-2-(1-hydroxypropyl)-4-(isopropyl(methyl)amino)cyclohexyl)pyrrolidin-2-one (190 mg) as an oil.
