Abstract:
A method of producing vinyl glycine comprising:(a) reacting allyl cyanide with anhydrous methanol in a molar ratio of 1:1 to 1:5 and in the presence of hydrochloric acid at a temperature from -20.degree. C. to 20.degree. C. to form methyl-3-butenylimidate hydrochloride;(b) reacting the methyl-3-butenylimidate hydrochloride formed in step (a) with sodium hypochlorite at a temperature from -40.degree. C. to 40.degree. C. to form methyl-N-chloro-3-butenylimidate; and(c) reacting the methyl-N-chloro-3-butenylimidate formed in step (b) with aqueous hydroxide at a temperature from -20.degree. C. up to refluxing temperature for 5 to 25 hours to form vinyl glycine.
