Reaction Steps

To a solution of 3-((S)-1-cyclopentyloxycarbonyl-3-methyl-butylamino)-piperidine-1-carboxylic acid tert-butyl ester (0.840 g, 2.20 mmol) in dichloromethane (5 mL) was added 4M hydrogen chloride in dioxane (10 mL). The reaction was stirred at room temperature for 90 minutes and then concentrated to give the product (184 mg, 24% yield). LC/MS: m/z 283 [M+H]+
