Potassium Carbonate → Methyl 3-(cyclopropylmethoxy)-4-methoxy-2-nitrobenzoate

Participants

Reaction Steps

(Bromomethyl)cyclopropane (136 g, 1.01 mol) and potassium carbonate (173 g, 1.25 mol) were added to a solution of methyl 3-hydroxy-4-methoxy-2-nitrobenzoate (190 g, 837 mmol) and dimethylformamide (1 L). The mixture was stirred at room temperature overnight and then quenched with water/ice (3 L). The resulting solids were collected by filtration, washed with water (500 mL×3), and then dried in an oven to give 220 g of methyl 3-(cyclopropylmethoxy)-4-methoxy-2-nitrobenzoate as a yellow solid. MS (ESI): 281.9.
