Reaction Conditions:

with monolith-SO₃H in toluene at 80; for 24 h;Inert atmosphere;

Steps:

Methylation of Various Carboxylic Acids (Table 3):

General procedure: To atest tube were added the carboxylic acid (500 mol), monolith-SO3H (100 wt%), and toluene (0.5 mL). Then, MeOH (30.3 L,750 mol) and additional toluene (0.5 mL) were added. Thereaction mixture was stirred under an Ar atmosphere (balloon)at 80 °C for 24 h, then passed through a cotton filter to removemonolith-SO3H and washed with Et2O (15 mL). The filtratewas concentrated in vacuo. The residue was purified by silica gel flash column chromatography (n-hexane/Et2O) to give thecorresponding methyl ester, if necessary. The 1H and 13CNMRspectra of the product were identical to those in the literature.
