실험 절차
To a stirred solution of 4,6-dichloro-5-nitropyrimidine (7 g, 36 mmol) and TEA (10 mL, 72 mmol) in DCM (60 mL) at 0° C. under N2 was added Bn2NH in 10 mL dropwise over 2 hrs. Stirring was continued for 30 min before the reaction mixture was diluted with water (100 mL). The layers were separated and the aqueous layer was extracted with DCM (50 mL×3). The combined organic layer was washed with water (100 mL×2) and brine (100 mL×1), dried over Na2SO4 and concentrated in vacuo. N,N-dibenzyl-6-chloro-5-nitropyrimidin-4-amine (1) (12.8 g, 100%) was obtained as a brown slurry. LC-MS (ESI): m/z (M+1) 355.
