Procedure

To a solution of 2,4,6-trimethylbenzoic acid (10 g, 61 mmol) in DMF (100 mL) were sequentially added potassium carbonate (17 g, 122 mmol) and allyl bromide (11 g, 91.5 mmol). The mixture was stirred at rt overnight before it was poured into water (˜1 L). The resulted precipitate was filtered and washed with water, then dried in vacuo to give allyl 2,4,6-trimethylbenzoate as a solid (10.2 g, 82%) which was nitrated and then reduced as shown for Example 14 (procedure B and C) to give allyl 3-amino-2,4,6-trimethylbenzoate.
