Reaction Steps

To t-butyl(3R)-3-((R)-1-((S)-4-(4-chlorophenyl)-4-hydroxy-3,3-dimethylpiperidin-1-yl)-3-methyl-1-oxobutan-2-ylcarbamoyl)-1-(2-hydroxyethyl)cyclopentylcarbamate (58 mg, 0.098 mmol) was added hydrogen chloride (4M in dioxane, 0.5 mL). The resulting mixture was stirred at room temperature for 1 hour. The reaction mixture was concentrated to yield (1R)-3-amino-N—((R)-1-((S)-4-(4-chlorophenyl)-4-hydroxy-3,3-dimethylpiperidin-1-yl)-3-methyl-1-oxobutan-2-yl)-3-(2-hydroxyethyl)cyclopentanecarboxamide, hydrogen chloride salt (50 mg, 0.094 mmol, 97% yield) as an oil. It was used as such for the next step without further purification. MS (ESI+) m/z 494 M+
