Reaction Steps

9-[(2,4-Diaminothieno[2,3-d]pyrimidin-5-yl)methyl]phenothiazine (Formula I: Ar=2,4-diaminothieno[2,3-d]pyrimidin-5-yl; W=CH2; X=N; Z=S; m=n=0) is prepared similarly to N-[(2,4-diaminothieno[2,3-d]pyrimidin-5-yl)methyl]-N,N-diphenylamine as disclosed in Example 11 above by using 2,4-diamino-5-methylthieno[2,3-d]pyrimidine (1.3 g, 7.4 mmol) in Step 1 and phenothiazine (159 mg, 0.8 mmol) in Step 3. The final product and its intermediates can be purified by chromatography.
