Reaction Steps

To a solution of 2-chloro-5-iodo-N-propylpyrimidin-4-amine (F1, 46.3 mg) in tetrahydrofuran (0.5 mL), a 9.8 mol/L solution of methylamine in methanol (0.5 mL) was added at room temperature, the reaction vessel was sealed, and then by using a microwave reaction system, the mixture was stirred at 80° C. for 30 minutes. The reaction mixture was cooled to room temperature, and then the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent, 40 to 27% hexane in ethyl acetate) to obtain 5-iodo-N2-methyl-N4-propylpyrimidine-2,4-diamine (F222, 32.4 mg) as white solid.
