실험 절차

A mixture of 2-chloro-5-nitropyrimidin-4-amine (1.0 g, 5.8 mmol) and methylamine (2.0 M solution in THF, 14 mL, 28 mmol) was allowed to stir in a sealed vessel for 1 h. The mixture was then heated to 60 deg. C. for 30 min. The reaction was cooled to ambient temperature, and an additional amount of methylamine (2.0 M solution in THF, 8 mL, 16 mmol) was added and the reaction was sealed and heated to 60 deg. C. for 30 min. The reaction was cooled, diluted with water, and the precipitate was collected by filtration. The solid was rinsed with small portions of water followed by diethyl ether. The material was dried in under reduced pressure to give N2-methyl-5-nitropyrimidine-2,4-diamine 48 as a light yellow solid. MS (ES+): 170 (M+H)+; Calc. for C5H7N5O2=169.14.
