Reaction Steps

4-Chloro-6-(1H-imidazol-1-yl)pyrimidine (4.0 g, 22.1 mmol) was split into two equal portions and separately placed into two sealed tubes with a solution of 7 N ammonia in methanol (40 mL). The tubes were sealed and heated at 65° C. for 20 h, then allowed to stand at room temperature for 3 days. The reactions were combined, concentrated and purified by flash chromatography on a 240 g silica gel cartridge with 40 to 100% EtOAc in hexane, then 0 to 50% MeOH in EtOAc to yield 6-(1H-imidazol-1-yl)pyrimidin-4-amine (1.43 g, 40%). LCMS: RT=0.39 min, MH+=162.1.
