실험 절차

N-{6-Bromo-1-[(4-methylphenyl)sulfonyl]-1H-indazol-4-yl}-2-{[(2R,6S)-2,6-dimethyl-4-morpholinyl]methyl}-1,3-thiazole-4-carboxamide (4 g), 2-(methyloxy)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinamine (1.8 g), sodium carbonate (2.8 g) and Pd(dppf)Cl2 (0.48 g) were weighed to a 500 ml round-bottomed flask and 1,4-dioxane (150 ml) and water (150 ml) were added. The reaction was heated to 80° C. for 2 hours. The reaction was cooled then passed through a 10 g silica cartridge, washing with DCM:methanol. The reaction was concentrated to leave only the aqueous phase. DCM was added and the product extracted. The DCM was passed through a hydrophobic frit, then evaporated to dryness. The residue was purified on silica chromatography eluting with 0-6% methanol in DCM over 30 mins. Product containing fractions were combined and evaporated to dryness. The residue was repurified by silica chromatography using a gradient of 1.5-5% methanol in DCM over 30 mins. Product containing fractions were combined and evaporated to dryness to give title compound (1.9 g).
