Procedure: Sodium nitrite (262 mg) dissolved in 1.0 ml of water was dropped, under cooling with ice, into a solution of 500 mg of 3-fluorophenylhydrazine hydrochloride in 2.5 ml of concentrated hydrochloric acid and 3.0 ml of diethyl ether. Temperature of the reaction solution was raised to room temperature followed by stirring for 3 hours. The reaction solution was diluted with diethyl ether, washed with water and then with a saturated saline solution and dried over sodium sulfate. The solvent was evaporated in vacuo to give 252 mg of the title compound as a brown oily crude product. was dropped washed with water with a saturated saline solution and dried over sodium sulfate The solvent was evaporated in vacuo
