Reaction Steps

Thionyl chloride (11 ml; 0.151 mol) was added to a suspension of 5-methyl-1H-indazole-3-carboxylic acid (12.2 g; 0.056 mol), prepared as described in J. Heterocyclic Chem. 1964, Vol. 1 (5) 239-241, in toluene (130 ml), and the reaction mixture was refluxed for 4 hours. The solvent was removed by evaporation under reduced pressure and the residue was taken up twice in toluene to give 12 g of the desired product.
