Procedure
To 2-methylcinnamic acid (100 g; 617 mmol) in 1.2L of DMF was added DBU (112.6 g; 740 mmol) and 15 min later methyl iodide (131.3 g; 925 mmol) and left overnight. The solution was diluted in ether and washed with HCl (10%), H2O and brine. The solvent was removed to give 106.8 g of the title compound.
