Reaction Steps
In the same way as described for Compound 212, step 3, using (4-morpholin-4-yl-phenyl)-(5-tributylstannanyl-imidazo[1,2-a]pyrazin-8-yl)-carbamic acid tert-butyl ester (0.25 g, 0.365 mmol), 5-bromo-thiazole-2-carboxylic acid amide (60.5 mg, 0.29 mmol) and Pd(PPh3)4 (63.3 mg, 0.055 mmol) in DMF. Purification by silica gel column chromatography eluting with 99:1 and 95:5 DCM:MeOH affords the title compound as a free base (27.4 mg, 49%).
