Cesium carbonate → Methyl 3-((2-hydroxy-2-methylpropyl)amino)-4-nitrobenzoate

Participants

Reaction Steps

To a solution of methyl 3-fluoro-4-nitrobenzoate (2.0 g, 10.04 mmol) in DMSO (10.04 mL) was added cesium carbonate (9.82 g, 30.1 mmol) and 1-amino-2-methylpropan-2-ol (0.985 g, 11.05 mmol). The reaction mixture was stirred at ambient temperature for 30 min. Saturated sodium bicarbonate and EtOAc were added to the mixture. The aqueous layer was extracted EtOAc (3×). The combined organics were washed with brine, dried over magnesium sulfate, filtered and concentrated to give the title compound without further purification (3.18 g): LC-MS [M+1]=269.2.
