Reaction Steps

To a solution of tropic acid (5.0 g, 30 mmol) in toluene:CH2Cl2 (150 mL; 2:1) was added DBU (4.6 g; 30 mmol), followed by MeI (4.3 g; 30 mmol). The mixture was stirred overnight, water was added and the phases were allowed to separate. The water phase was extracted wit h ether, and the combined organic phase was washed with NaHCO3(aq, HCe/aq and water, dried was Na2SO4) and concentrated to yield 0.95 g (18%) of the sub-title compound.
