To a 4 M 1,4-dioxane solution (60 mL) of hydrogen chloride, (2S,3S)—N-cyclopropyl-3-(t-butoxycarbonyl)amino-2-hydroxyhexanoic acid amide (4.5 g) was added. A solid of the product aggregated to form a lump after about 5 minutes, and the flowability of the reaction liquid worsened. After the disappearance of the starting material, the solvent was evaporated away with an evaporator to obtain a concentrated product of (2S,3S)—N-cyclopropyl-3-amino-2-hydroxyhexanoic acid amide hydrochloride (chemical purity: 89.8 area %).
