Procedure

A mixture of 1,3,5-triazine (1 g, 12.3 mmol) and 3-Fluorophenylhydrazine hydrochloride (2 g, 12.3 mmol) in ethanol (20 mL) is heated at reflux overnight. After concentrating, ethyl acetate is added, the mixture is washed with aqueous bicarbonate followed by saturated aqueous sodium chloride, dried (MgSO4), and concentrated to give 1.8 g of crude 1-(3-Fluorophenyl)-1,2,4-triazole. 1H NMR (CDCl3): δ 8.57 (s, 1H), 8.12 (s, 1H), 7.46-7.51 (m, 3H), 7.08-7.15 (m, 1H). LCMS 164.1 (MH+).
