PROCEDURE

实验过程

6-Chloro-3-methoxy-4-methyl-1-trityl-1H-pyrazolo[4,3-c]pyridine (1.5 g, 3.41 mmol) was dissolved in CCl4 (10 mL), charged with NBS (637 mg, 3.58 mmol) and AlBN (56.0 mg, 0.341 mmol), and heated to 70° C. overnight. The reaction was diluted with DCM (10 mL) and purified by flash chromatography (5-25% EtOAc/hexanes) to give 4-(bromomethyl)-6-chloro-3-methoxy-1-trityl-1H-pyrazolo[4,3-c]pyridine. MS ESI calc'd. for C27H21BrClN3O [M+1]+519. found 519.
