Methyl 2-((1R,2S)-2-(tert-butoxycarbonylamino)cyclohexylamino)-4-methyl-6-(3-(trifluoromethyl)phenylamino)pyrimidine-5-carboxylate (104 mg, 0.199 mmol), which was prepared in a manner similar to methyl 2-((1R,2S)-2-(tert-butoxycarbonyl-amino)cyclohexylamino)-4-methyl-6-(m-tolylamino)pyrimidine-5-carboxylate in step B of EXAMPLE 1 using 3-(trifluoromethyl)aniline in place of m-toluidine in step A of the example, was combined with 1-bromopyrrolidine-2,5-dione (53.0 mg, 0.298 mmol) and benzoic peroxyanhydride (48.1 mg, 0.199 mmol) in CCl4 (10 mL), and the resulting mixture was stirred at 70° C. for 18 h. The reaction was stopped. The mixture was concentrated under reduced pressure, separated between water and EtOAc. The organic extract was dried and concentrated under reduced pressure to give the title compound, which was used in the next step without further purification. [M+H] calc'd for C25H31BrN5O4, 603. found, 604.
