Reaction Steps

A 6 ml portion of NMP solution containing 600 mg of 2-(benzotriazol-1-yloxy)-4-[(3-methylphenyl)amino]pyrimidine-5-carboxamide was mixed with 538 mg of 2-(3-bromo-4-hydroxyphenyl)ethylamine and 0.72 ml of diisopropylethylamine, followed by stirring at 80° C. for 2 hours. The reaction mixture was cooled down to room temperature, and then mixed with water and extracted with ethyl acetate. The organic layer was washed with saturated brine, the solvent was evaporated, and then the resulting residue was recrystallized (ethanol-THF) to obtain 200 mg of 2-{[2-(3-bromo-4-hydroxyphenyl)ethyl]amino}-4-[(3-methylphenyl)amino]pyrimidine-5-carboxamide as colorless crystals.
