Reaction Steps

2-Vinyloxy Ethyl Phthalimide was prepared via reacting 2-chloroethyl vinyl ether (25 g, 0.24 mol) and potassium phthalimide (25 g, 0.135 mol) in 100° C. DMF(75 mL) using tetra n-butyl ammonium bromide (0.5 g) as the phase transfer catalyst. This solution was heated for six hours and then crashed out in water and filtered. This solid was then recrystallized twice from methanol to give white crystals.
