Reaction Steps
To a solution of 1H-benzo[d][1,2,3]triazol-5-amine (1.85 g, 13.8 mmol, Alfa Aesar) in THF (10 mL) and CH3CN (8 mL) was added pyridine (1.34 mL, 16.6 mmol) followed by phenyl chloroformate (2.27 mL, 14.5 mmol) slowly. The reaction was stirred overnight. The reaction was concentrated to give an oil, which was partitioned between CH2Cl2 and water. The organic layer was dried using a SPE phase separator and concentrated to give a solid. This was taken up in CH2Cl2 and the precipitate was filtered to give the desired product (2.0 g, 57%) which was used without purification. MS M+1: 256.06.
