실험 절차

To a stirred solution of the 4-[5-(3-amino-5-methylphenyl)-1,3-thiazol-2-yl]-1,4-diazepan-2-one (Intermediate XX, 165 mg, 0.55 mmol) and tert-butyl (3R)-3-[(2-chloropyrimidin-4-yl)oxy]pyrrolidine-1-carboxylate (164 mg, 0.55 mmol) in dioxane (2.7 ml) was added AcOH (66 μl, 1.15 mmol). The mixture was heated to 120° C. for 5 h, treated with additional portion of AcOH (66 μl, 1.15 mmol), and left to stir overnight. Additional AcOH (66 μl, 1.15 mmol) was then added and the resultant mixture was left to stir overnight. The mixture was then cooled to room temperature, diluted with saturated sodium bicarbonate solution, and extracted with ethyl acetate (×3). The combined organics were washed with brine, dried over sodium sulfate, concentrated, and purified by Combiflash. (ethyl acetate/hexanes) to afford 80 mg (0.14 mmol, 26% yield) of tert-butyl (3R)-3-{[2-({3-methyl-5-[2-(3-oxo-1,4-diazepan-1-yl)-1,3-thiazol-5-yl]phenyl}amino)pyrimidin-4-yl]oxy}pyrrolidine-1-carboxylate.
