Triphenylphosphine (47 mg, 0.17 mmol) was added to a stirred solution of {3-[5-amino-6-(5-phenyl-4H-1,2,4-triazol-3-yl) pyrazine-2-yl]phenyl}methanol (50 mg, 0.14 mmol) and N-[(1S)-2,3-dihydro-1H-inden-1-yl]-2,4-dinitrobenzen sulfonamide (60 mg, 0.16 mmol) in THF. Diethyl azodicarboxylate (31 mg, 0.17 mmol) was then added and mixture was stirred at ambient temperature 4 h. Ethyl acetate (20 mL) was added, and the organic layer was washed with saturated aqueous sodium chloride, and then dried (Na2SO4). Filtration and concentration followed by chromatography on silica gel afforded the title compound: MS (EI) for C35H29N9O6S: 704 (MH+).
