Procedure
A mixture of 3-{8-[4-(Morpholine-4-carbonyl)-phenylamino]-imidazo[1,2-a]pyrazin-6-yl}-benzoic acid (9) (0.23 mmol), benzotriazol-1-yloxy-tris(dimethylamino)-phosphonium hexafluorophosphate reagent (0.23 mmol) and N,N′-diisopropylethylamine (0.77 mmol) is stirred under N2 for 15 min. in 1 mL DMF. 4-tert-Butyl-phenylamine (0.37 mmol) is added and the reaction stirred at rt for 8 hrs. The reaction is partitioned between ethyl acetate (15 mL) and water (15 mL) and the ethyl acetate layer washed with water (2×15 mL) and brine (1×15 mL). The organic layer is dried over sodium sulfate and the solvent removed in vacuo. The resulting crude oil is dissolved in 1 ml CH2Cl2 and clean yellow solid is precipitated by slow addition of diethyl ether, yielding the final product, (10) N-(4-tert-Butyl-phenyl)-3-{8-[4-(morpholine-4-carbonyl)-phenylamino]-imidazo[1,2-a]pyrazin-6-yl}-benzamide.
