実験手順

Example 1, Alternative Preparation, Step 6: To a solution containing acetamide 10 (˜61 g) in i-PrOH (˜625 mL) was added 10% Pd/C wet catalyst (2.5 g) and the suspension was hydrogenated at 30 psig and approx. 25° C. for at least 2 h. Upon completion (HPLC), the catalyst was removed by filtration and the filtrate was concentrated to approx. 550 mL. Water (8.8 mL) was added, followed by 5.6 N hydrochloric acid in i-PrOH solution (69.5 mL). The resulting slurry was held at room temperature overnight. The product was isolated by filtration and the cake was rinsed with i-PrOH (2×100 mL) and dried in vacuo to constant weight at ˜50° C. to give N-[(1R,2S,5R)-2-((S)-3-amino-2-oxo-pyrrolidin-1-yl)-5-(isopropyl-methyl-amino)-cyclohexyl]-acetamide 11 (55.6 g, 97% yield) as its hydrochloric acid salt (73.6% free base assay, HPLC).
