Reaction Steps
Benzyl N-[4-(6-aminopyrimidin-4-ylamino)phenyl]carbamate (313 mg) was dissolved in tetrahydrofuran (10 ml) under a nitrogen atmosphere, and then triethylamine (0.78 ml) and phenyl chloroformate (0.35 ml) were added dropwise thereto while cooling in an ice bath, followed by stirring at room temperature for 30 min. To the reaction mixture were added pyrrolidine (1.0 ml) and N,N-dimethylformamide (2 ml), followed by further stirring at room temperature overnight. The reaction mixture was partitioned between ethyl acetate and water. The organic layer was washed with brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under a reduced pressure to give a residue, which was then purified by silica gel column chromatography (eluent; ethyl acetate, then ethyl acetate:methanol=95:5) to provide the titled compound (210 mg, 52%) as pale yellow powder.
