Reaktionsschritte
To a solution of 4 g (0.02 mol) of t-butyl glycinate and 4 ml of pyridine in 100 ml of methylene dichloride at 0° under nitrogen was added a solution of 2.01 ml (0.024 mol) of bromoacetyl bromide in 10 ml of methylene dichloride. After the addition, the mixture was stirred for 3 hrs and poured into 1 N aqueous hydrochloride. The organic layer was separated and then washed successively with 1 N HCl, water and brine. After drying over anhydrous sodium sulfate, the mixture was evaporated to dryness in vacuo to yield 6 g of a light brown product, which upon recrystallization from hexane-ethyl acetate, yielded a product with mp 90°-91°.
