실험 절차

6-Chloro-3-(4-ethylphenylamino)benzo[d]isoxazole-7-carboxylic acid (0.195 g, 0.615 mmol) was dissolved in DMF, followed by TEA (0.223 ml, 1.61 mmol) and HATU (0.285 g, 0.749 mmol). The mixture was allowed to stir for 5 min before adding pyrimidin-5-amine (0.0509 g, 0.535 mmol) and the mixture was heated to 50° C. overnight. The mixture was then cooled to RT, partitioned between EtOAc/brine, the layers were separated, and the aqueous was extracted with EtOAc (3×). The combined organics were washed with H2O and brine, filtered and concentrated. The crude material was purified by silica gel chromatography using 20:1 DCM/MeOH to give 6-Chloro-3-(4-ethylphenylamino)-N-(pyrimidin-5-yl)benzo[d]isoxazole-7-carboxamide as a light brown solid. MS calculated 393.8, found M+H+=394.1.
