Reaction Steps

A solution of 13.98 g (0.0841 mol) of methyl 3-hydroxy-2-methylbenzoate in 120 mL of DMF was cooled in ice and treated dropwise with 200 mL (0.1 mol) of a 0.5 M solution of KHMDS in toluene. After stirring for 10 minutes, 7.8 mL (0.126 mol) of methyl iodide was added and the solution allowed to stir at room temperature overnight. The solution was diluted with EtOAc and washed twice with 6% HCl, 3 times with H2O, 10% NaHSO3, then saturated NaCl. Drying over MgSO4 and removal of the solvent under reduced pressure left 14.22 g (93.8% yield) of the product as a golden oil. The structure was confirmed by NMR and mass spectroscopy. MS m/z 181 (M+H+).
