Reaction Steps

To a solution of N,N-carbonyidiimidazole (0.96 g, 5.0 mmol) and imidazole (0.68 g, 10 mmol) in tetrahydrofuran (10 mL) at 0° C. was added 4-aminobiphenyl (1.0 g, 5.9 mmol) in tetrahydrofuran (10 mL). After stirring at 0° C. for 10 min 5-(2-aminophenyl)tetrazole (1.14 g, 7.1 mmol) was added. The reaction was stirred for another 4 hours and filtered. The filtrate was evaporated to dryness and the crude product purified by column chromatography. A yield of 0.28 g was obtained. M.p. 224-226° C.
