Reaction Steps

To a suspension of 3-carboxyphthalimide (10 g) in ether (50 ml), a solution of diazomethane in ether was added slowly until a faint yellow colouration persisted. Excess of diazomethane was destroyed with acetic acid and the reaction mixture was evaporated to yield the desired compound.
