1,2,3,4-Tetrahydroquinoline (10 g, 75 mmol) was dissolved in 50 mL 3N HCl at 0° C. The reaction mixture was stirred for 5 min. at 0° C., a solution of sodium nitrite (6.22 g, 90 mmol) in water was added at the same temperature, and then the reaction mixture was stirred for 2 h at RT. After completion of reaction, water was added and the mixture extracted with EtOAc (2×200 mL). The combined organic layers were washed with water, dried over sodium sulfate and concentrated under vacuum to obtain 10 g of product.
