The mixture was stirred at rt for 3 h. The reaction was filtered and the filtrate was washed with Na2CO3, 0.5N HCl, and brine. The organic layer was dried over Na2SO4 and Concentrated to give N—((R)-1-((S)-4-(4-chlorophenyl)-4-hydroxy-3,3-dimethylpiperidin-1-yl)-3-methyl-1-oxobutan-2-yl)formamide (76 mg, 0.207 mmol, 70.0% yield).
