실험 절차

To a solution of 223 g (1 mol) of 2-bromopropiophenone in 300 ml of acetonitrile is added dropwise to a boiling mixture of 414 g (6 mols) of triazole and 1,200 ml of acetonitrile, and the mixture is heated at the boil for 8 hours. Thereafter, the mixture is evaporated down in vacuo, the residue is taken up in 750 ml of dichloromethane and 750 ml of water, and the organic phase is washed with several 500 ml portions of water and dried over anhydrous sodium sulphate. After the solvent has been distilled off, the remaining residue is distilled in vacuo. 111 g (55% of theory) of 2-(1,2,4-triazol-1-yl)-propiophenone of boiling point 133° C./0.15 mbar and of melting point 117° C. are obtained. ##STR21##
