Reaction Steps

Deprotection of 6.05 g (18.3 mmol) of 4-(1-ethoxycarbonyl-1-methyl-ethylsulfanyl)-piperidine-1-carboxylic acid tert-butyl ester is achieved by treatment with 4M aqueous HCl solution (9.13 mL) in dioxane (40 mL) at room temperature for 18 h. The reaction mixture is concentrated to afford 4.47 g of 2-methyl-2-(piperidin-4-ylsulfanyl)-propionic acid ethyl ester as its hydrochloride salt as a brown oil. Yield: 92%; ES-MS: m/z 232 [M+H]
