반응 단계
A round-bottomed flask was charged with 2-propanol (595 mL), and nitrogen was bubbled through the 2-propanol for 2 hours. Pd2(dba)3 (1.63 g, 1.78 mmol) and di-tert-butyl(2′,4′,6′-triisopropyl-3,4,5,6-tetramethylbiphenyl-2-yl)phosphine (3.43 g, 7.14 mmol) were added, and the mixture was stirred for 20 minutes. Potassium acetate (17.5 g, 178 mmol), 3-amino-1H-pyrazole-4-carboxamide (15.0 g, 119 mmol), and isopropyl 4-bromobenzoate (34.7 g, 143 mmol) were then added, and the reaction mixture was heated to 75° C. for 6.5 hours. The reaction mixture was then cooled to 23° C., diluted with EtOAc (500 mL), and filtered through celite. The filtrate was adsorbed onto silica gel in vacuo and purified by MPLC on silica gel (using a gradient elution of 30-90%, EtOAc/hexanes) to afford the title compound.
