Procedure
Concentrated H2SO4 (3.4 mL) was added dropwise to a solution of 4-amino-3-ethylbenzonitrile (6.84 mmol) in H2O (12 mL) at 0° C. A solution of NaNO2 (7.52 mmol) in H2O (5 mL) was added dropwise at 0° C. to the resulting mixture. The reaction was stirred at 0° C. for 30 min and at 100° C. for 2 h. The mixture was cooled to room temperature and extracted with EtOAc. The organic layer was washed (H2O), dried and concentrated to yield the desired product.
