Reaction Steps
NaH (0.45 g of 55% suspension in mineral oil) is added to anhydrous DMF under nitrogen atmosphere. Tetrazole (1.1 g) is added and the mixture is gently heated for 20 minutes. The mixture is cooled to room temperature and 1-chloro-1-(4-cyanophenyl)3-(4-fluorophenyl)propane (1.53 g) is added. The reaction mixture is then heated for 6 hours. Water is added and the products are extracted into ethyl acetate. After drying and solvent evaporation the products are purified by flash chromatography. Elution, staring with pure methylene chloride with increasing methanol content, affords first 2-[1-(4-cyanophenyl)-3-(4-fluorophenyl)propyl]tetrazole which 1H NMR spectra is as follows:
