반응 단계

2,4,6-Trichloro-s-triazine (1, 1 g, 5.4 mmol), and ethylamine hydrochloride (0.44 g, 5.4 mmol) were combined in a round bottom flask and cooled to −5° C. using an ice-salt bath. To the cooled, stirred solution was added N,N-diisopropylethylamine (1.88 mL, 10.8 mmol). The resultant yellow colored solution was stirred at −5° C. for 1 h, the solvents removed under reduced pressure, and the resultant residue was dissolved in 1:1 v/v of ethyl acetate and water. The organic layer was separated, washed with saturated solution of NaHCO3, and dried over Na2SO4. The organic solvent was removed under reduced pressure to yield an orange colored solid. The solid was triturated with hexane to yield the product 2 as a yellow-orange powder (0.7 g) with a yield of 68%.
