Dimethyl Sulfoxide → 3-{[3-{[(5-Bromo-2-thienyl)sulfonyl]amino}-4-(methyloxy)-1H-indazol-1-yl]methyl}benzamide

Participants

Reaction Steps

3-{[3-Amino-4-(methyloxy)-1H-indazol-1-yl]methyl}benzamide (for a preparation see Intermediate 12) (22 mg, 0.07 mmol) was dissolved in pyridine (1.6 mL) and added to 5-bromo-2-thiophenesulfonyl chloride (27 mg, 0.1 mmol). The reaction mixture was shaken at room temperature for 5 min and then stood overnight at room temperature. DMSO (0.2 mL) was added to the reaction mixture and purified by MDAP on Atlantis column using Acetonitrile Water with a Formic acid modifier. The solvent was evaporated in vacuo using the Genevac to give the title compound (4.6 mg, 12%) LCMS (System A) RT=1.04 min, ES+ve m/z 521/523 (M+H)+.
