Hydrochloric Acid → Methyl 2-aminopent-4-enoate--hydrogen chloride (1/1)

Participants

Reaction Steps

HCl (g) was bubbled through a solution of DL-allylglycine (2.0 g, 17.4 mmol) in methanol (50 mL) at room temperature. The reaction was stirred overnight, concentrated in vacuo, taken up in acetonitrile (50 mL), and re-concentrated to give 2-amino-pent-4-enoic acid methyl ester hydrochloride salt (2.8 g, 100%) as an oil. MS found: (M+CH3CN)+=171.
