実験手順

To a cooled (0° C.) solution of 6-chloropyrimidine-4-carbonyl chloride in DCM (60 mL), obtained as described above for Intermediate 7, step 1 (798 mg; 4.51 mmol) was added dropwise, during a period of 30 minutes, a solution of 5-aminoindazole (Aldrich, 500 mg; 3.76 mmol) and DIEA (1.29 ml; 7.51 mmol) in dry DMF (5 mL). At the end of addition the reaction mixture was concentrated in vacuo, diluted with water and extracted with EtOAc. A white precipitate separated from the organic phase. It was filtered and dried in vacuo to afford the title compound as a beige solid.
