Versuchsvorschrift
A suspension of 2-chloro-6-(4-methanesulfonyl-piperazin-1-ylmethyl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidine, prepared via General Procedure B-3, (144 mg, 0.33 mmol), 5-tributylstannanyl-thiazole (187 mg, 0.5 mmol), and Pd(PPh3)4 (19 mg, 0.017 mmol) in anhydrous DMA was heated in a microwave at 150° C. for 10 mins. The crude reaction was loaded onto a preconditioned SCX cartridge, washing the cartridge with methanol and dichloromethane before eluting with 7N ammonia in methanol to give crude material. This was purified by on silica using 5% methanol in ethyl acetate as the eluent to give 152 as an off-white solid (80 mg, 50%). NMR (CDCl3, 400 MHz), 2.68-2.72 (4H, m), 2.83 (3H, s), 3.32-3.36 (4H, m), 3.88-3.93 (6H, m), 4.03-4.06 (4H, m), 7.32 (1H, s), 8.67 (1H, m), 8.84 (1H, s). MS: (ESI+): MH+=481
