반응 단계
4-Fluoro-3-tert-butoxycarbonylamino-1-butanoic acid (545 mg, 2.46 mmoles) is dissolved in dry ether (20 ml) saturated with hydrogen chloride gas. After a few minutes, the solution becomes turbid and white crystals start to precipitate. Recrystallization from ethanol by addition of diethylether affords 4-fluoro-3-amino-1-butanoic acid hydrochloride (265 mg, 68%), m.p. 152°-153° C. (dec).
