Procedure

7-Methyl-2-(methylthio)-4-morpholino-6-((4-N-methylsulfonylpiperazin-1-yl)methyl)thieno[3,2-d]pyrimidine (0.29 mM) was added to 4-tributylstannyl-2,6-diacetylaminopyridine dissolved in 10 mL 1,2-DME followed by the addition of Cu(I)Br-dimethylsulfide and stirred at room temperature for ten minutes. Finally, Pd(PPH3)4 was added and the reaction mixture was heated to reflux under N2 for 2 hours. Complete product formation was confirmed by LCMS. The reaction was diluted with EtOAc, extracted 1× with water and 1× with 1 M HCl. The combined aqueous layers were basified with 10% w/w KOH and extracted the product with EtOAc, dried over MgSO4, and concentrated in vacuo. This crude product was dissolved in 2 N HCl and heated to reflux for 12 hours to remove the acetyl groups and after concentrating in vacuo and HPLC purification gave 279. MS (Q1) 506 (M+)
