Reaction Steps

A mixture of 4,4″-Dichloro-[1,1′;3′,1″]terphenyl-5′-carbonitrile (50 mg, 0.15 mmol), sodium azide (20 mg, 0.31 mmol) and ammonium chloride (16 mg, 0.31 mmol) in DMF (1 mL) was heated at 100° C. for 16 h. The reaction mixture was acidified with 1M HCl solution poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried (Na2SO4) and the solvent was removed in vacuo to give 5-(4,4″-dichloro-[1,1′;3′,1″]terphenyl-5′-yl)-1H-tetrazole yield 36 mg (64%) as an off-white solid. 1H NMR (DMSO) δ 7.49 (d, 2H), 7.23 (t, 1H), 7.17 (s br, 1H), 6.96-6.99 (m, 4H), 6.71-6.74 (m, 4H), LCMS method A R.T. 3.5
