Reaction Steps

9-[(2,4-Diaminofuro[2,3-d]pyrimidin-5-yl)methyl]phenothiazine (Formula I: Ar=2,4-diaminofuro[2,3-d]pyrimidin-5-yl; W=CH2; X=N; Z=S; m=n=0) is prepared similarly to N-[(2,4-diaminofuro[2,3-d]pyrimidin-5-yl)methyl]-N,N-diphenylamine as disclosed above by using phenothiazine (159 mg, 0.8 mmol), NaH (50 mg, 2.1 mmol), and 2,4-diamino-5-chloromethylfuro[2,3-d]pyrimidine (60 mg, 0.3 mmol). The product can be purified by chromatography.
