实验步骤: 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. the reaction was concentrated

反应条件: temp:23.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of methyl 3-(cyclopentyloxy)-4-methoxy-2-nitrobenzoate (750 mg, 2.54 mmol), 10% Pd/C (50% H2O, 500 mg, 0.23 mmol Pd), and methanol (10 mL) was stirred vigorously at 23° C. under an atmosphere of H2. After 21 h, the mixture was filtered through Celite and concentrated to give methyl 2-amino-3-(cyclopentyloxy)-4-methoxybenzoate: MS (ESI): 266.5. the mixture was filtered through Celite concentrated
