실험 절차

A mixture of 4,4′-(6-chloro-1,3,5-triazine-2,4-diyl)dimorpholine (1.40 g, 4.90 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (2.62 g, 11.9 mmol) and tetrakis (triphenylphosphine) palladium (0) (282 mg, 0.240 mmol) in 2M sodium carbonate aqueous solution (10 mL, 20 mmol) and 40 mL of DME was stirred at 80° C. for 2 hr. The reaction mixture was diluted with 300 mL of ethyl acetate and washed with water. The organic layer was concentrated and purified by flash chromatography (ISCO, 120 g silica gel column, eluting with 0-100% EtOAc/Hexane) to give 4-(4,6-dimorpholino-1,3,5-triazin-2-yl)aniline (0.68 g, 40% yield). HPLC: Rt=2.09 min; MS 343 [M+H].
