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 1,4-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]
