실험 절차

A solution of {1-[(trimethylsilyl)methyl]-1H-1,2,3-triazol-4-yl}methanol (241 mg, 1.30 mmol), methyl 4-({[(2,4-dinitrophenyl)sulfonyl]amino}methyl)benzoate (514 mg, 1.30 mmol), triphenylphosphine (409 mg, 1.56 mmol) and benzene (4.34 mL) was treated with diethylazodicarboxylate (247 uL, 1.56 mmol). After one hour additional portions of triphenylphosphine (204 mg, 0.780 mmol) and diethylazodicarboxylate (124 uL, 0.780 mmol) The reaction was diluted with EtOAc and washed with 2M aq. HCl 2×, water, brine, dried (MgSO4) and concentrated to afford a brown oil used crude in the next reaction. MS: cal'd 563 (MH+), exp 563 (MH+).
