実験手順

To a stirred solution of (2RS,5SR)-5-(4-fluoro-phenyl)-1-(toluene-4-sulfonyl)-pyrrolidine-2-carbonitrile (0.70 g, 2.03 mmol) in DMF (25 ml) was added at room temperature sodium azide (0.40 g, 6.10 mmol) and triethylamine hydrochloride (0.42 g, 3.05 mmol) and the reaction mixture was stirred at 120° C. for 6 h. The mixture was poured in water (100 ml), acidified (2 N HCl) and the formed solid was collected to give (2RS,5SR)-5-[5-(4-fluoro-phenyl)-1-(toluene-4-sulfonyl)-pyrrolidin-2-yl]-2H-tetrazole (0.73 g, yield 93%) as an off-white solid, m.p. 150° C.
