Reaction Steps

9-[(2,4-Diaminopyrido[2,3-d]pyrimidin-6-yl)methyl]-9,10-dihydrodibenz-[b,f]azepine (Formula I: Ar=2,4-diaminopyrido[2,3-d]pyrimidin-6-yl; W=CH2; X=N; Z=CH2=CH2; m=n=0) is prepared similarly to N-[(2,4-diaminopteridin-6-yl)methyl]-N,N-diphenylamine as disclosed above by using 9,10-dihydrodibenz[b,f]azepine (158 mg, 0.8 mmol), NaH (50 mg, 2.1 mmol) and 2,4-diamino-6-bromomethylpyrido[2,3-d]pyrimidine hydrobromide (100 mg, 0.3 mmol). The product can be purified by chromatography.
