实验步骤: To an ice cold solution of 4-(dimethylamino)-4-oxobutanoic acid (0.174 g, 1.20 mmol) in CH2Cl2 (2 mL) was added DIPEA (0.208 mL, 1.120 mmol) followed by isobutyl chloroformate (0.138 mL, 1.06 mmol). The mixture was stirred for 10 minutes, and the resulting mixed anhydride was added to a solution of N,3-dimethyl-1-(pyridin-3-yl)-1H-pyrazol-4-amine (0.100 g, 0.531 mmol) in CH2Cl2 (0.66 mL). The reaction mixture was stirred at room temperature (about 22° C.) for one hour. The crude reaction mixture was concentrated and purified via reverse phase column chromatography (0%-100% acetonitrile (MeCN)/water) to give the desired product F62 as a white solid (0.155 g, 83%). The reaction mixture was stirred at room temperature (about 22° C.) for one hour The crude reaction mixture was concentrated purified via reverse phase column chromatography (0%-100% acetonitrile (MeCN)/water)
