Versuchsvorschrift

A mixture of 2-[1-(7-morpholin-4-yl-5-(tributylstannanyl)thiazolo[5,4-d]pyrimidin-2-ylmethyl)piperidin-4-yl]propan-2-ol (118 mg, 0.18 mmol), 5-bromo-8-methylimidazo[1,2-a]pyridine (45 mg, 0.21 mmol), Pd(PPh3)4 (20 mg, 0.02 mmol) and copper(I) thiophene-2-carboxylate (7 mg, 0.035 mmol) in dioxane (2 mL) was purged with argon gas then heated at 150° C., for 20 min, in a microwave reactor. The reaction mixture was loaded onto an Isolute® SCX-2 cartridge (10 g). The cartridge was washed with MeOH then the desired product was eluted with 2 M NH3 in MeOH. The resulting residue was purified by flash chromatography (Si—PPC, MeOH:DCM, gradient 0:100 to 10:90) to give 244 as an off-white solid (80 mg, 89%).
