Reaction Steps
tert-Butyl 2-[N-(3-methoxyphenyl)-2-phthalimidoacetamido] acetate may be prepared in the following manner: phthalimide potassium salt (7.5 g) is added to a solution of tert-butyl 2-[2-chloro-N-(3-methoxyphenyl)acetamido]acetate (6.3 g) in dimethylformamide (100 cc). The mixture is stirred at a temperature in the region of 100° C. for 5 hours and then poured into water (1000 cc). The insoluble product is separated by filtration, washed with water (3×60 cc) and dried in the air. After recrystallisation in diisopropyl ether, tert-butyl 2-[N-(3-methoxyphenyl)-2-phthalimidoacetamido]acetate (6.7 g), m p 138° C. is obtained.
