Versuchsvorschrift
To a solution of 2 mmole of beta-difluoromethyl beta-alanine in 5 ml of 1 N sodium hydroxide at 0° C. are added simultaneously from two syringes 160 mg of acetyl chloride diluted in 1 ml of dioxane and 2 ml of 1 N sodium hydroxide. After 30 minutes at 0° C. the solution is acidified by the addition of 6 N hydrochloric acid, then extracted well with dichloromethane. The organic phase is dried and concentrated to afford 3-difluoromethyl-3-(1-oxo-ethylamino) propionic acid.
