実験手順
To a solution of 2-vinylglutamic acid (350 mg, 2 mM) in 5 ml of 1 N sodium hydroxide at 0° C. are added simultaneously from 2 syringes acetyl chloride (160 mg) diluted in dioxane (1 ml) and 2 ml of 1 N sodium hydroxide. After 30 minutes at 0° the solution is acidified by the addition of 3 N hydrochloric acid, then extracted well with dichloromethane. The organic phase is dried and concentrated to afford N-acetyl-2-vinylglutamic acid.
