반응 단계

To a stirred solution of 250 mg (0.77 mmol) trifluoromethanesulfonic acid 2-amino-6-furan-2-yl-5-methyl-pyrimidin-4-yl ester in 10 ml DME in a pressure tube was added 0.63 ml (5.77 mmol) benzylamine and the mixture heated at 80° C. for 16 hours. The reaction mixture was then poured onto 80 ml water and cooled to 0° C. The resulting crystals were collected by filtration and washed sequentially with water, ether/hexane and a minimum quantity of ice-cold ether to afford 140 mg (65%) N4-benzyl-6-furan-2-yl-5-methyl-pyrimidine-2,4-diamine as a white crystalline solid. ES-MS m/e (%): 281 (M+H+, 100).
