Reaction Steps

A round bottomed flask was charged with 3-amino-3-methylbutanoic acid (1.452 g, 12.39 mmol), potassium carbonate (2.57 g, 18.59 mmol), and a stirbar. EtOH (20 mL, 0.5 M) was added, followed by 1-fluoro-2-nitrobenzene (2.84 ml, 15.49 mmol), and the solution was stirred at reflux overnight. The mixture was cooled, concentrated with celite, and purified by silica gel chromatography (eluting with methylene chloride/methanol/ammonium hydroxide) to yield 3-methyl-3-(2-nitrophenylamino)butanoic acid as a red solid (2.32 g, 9.73 mmol, 79%).
