Cyanuric chloride → N-(3-azidopropyl)-4,6-dichloro-1,3,5-triazin-2-amine

Participants

Reaction Steps

To a solution of cyanuric chloride (18.42 g, 0.10 mol) in acetone (180 mL) in an ice-water bath was added diisopropylethylamine (DIPEA) (12.92 g, 0.10 mol). 1-azido-3-aminopropane (5.00 g, 0.050 mol) in acetone (50 mL) was added slowly over 2 hours. The reaction was stirred at room temperature overnight. The solvent was removed under reduced pressure. The residue was dissolved in CH2Cl2, washed with water, dried (Na2SO4) and rotary evaporated. The resulting residue was purified by column chromatography on silica gel (eluent CH2Cl2) to give 1 as a white solid (5.62 g, 45%): ESI-MS m/z 248.1 (M+H+) calculated for C6H8Cl2N7 248.0.
