反応手順

To a solution of 1-(2-aminopyrimidin-4-yl)-6-iodoindazole-3-carboxylic acid (1.00 g, 2.62 mmol) in DCM (10 mL), was added thionyl chloride (1.9 ml, 26.24 mmol)) followed by a drop of DMF. The mixture was stirred at 50° C. for 45 minutes. The reaction mixture was concentrated in vacuo and DCM (5 mL) was added and the concentration repeated (×2). The crude acid chloride was used directly in the next step: LC-MS m/z=+395.95 (M+H)+(after conversion to methyl ester derivative)
