Reaction Steps

To a suspension of 10 g (0.0651 mol) of 4-methylsalicylic acid in 150 mL of methanol was added 50 mL of ethereal hydrochloric acid. The reaction mixture was heated at 60° C. for 60 hours. The solvent was removed under vacuum. After adding hexane-ethyl acetate, the resulting solid was filtered and the filtrate was evaporated to give 10.2 g (94%) of product as an oil.
