Reaction Steps
A solution of methyl 2-amino-3-(cyclopentyloxy)-4-methoxybenzoate (5.54 g, 20.9 mmol), acetic anhydride (21.0 mL, 222 mmol), and dioxane (35 mL) was heated at 40° C. under N2, for 17 h and then allowed to cool to room temperature. Water (10 mL) was added, and after 15 min of stirring, the reaction was concentrated to give methyl 2-acetamido-3-(cyclopentyloxy)-4-methoxybenzoate: MS (ESI): 307.9.
