Procedure

To a stirred solution of 3-(4-fluorophenyl)-6-methyl-1,2,3,4-tetrahydroquinoline (0.28 g, 0.00166 mol) in ethanol (1 mL) was added 1N hydrochloric acid (1 mL), and the reaction mixture was cooled to 0° C. Sodium nitrite (0.160 g, 0.00232 mol) in water (3 mL) was added at 0° C., and the mixture stirred for 1 h at RT. The reaction was monitored by TLC. After completion, solvent was removed under reduced pressure to obtain product as a brown colored oil (0.28 g, 89% yield).
