Procedure

A solution of 1-benzyl-3-methyl-indazole-6-carboxylic acid [0.15 g, Reference Example 28(o)] in dichloromethane (20 ml) was treated with dimethylformamide (2 drops) then with oxalyl chloride (1.69 ml). After stirring for 2 hours the reaction mixture was evaporated and the residue was dried under high vacuum to give the title compound (0.16 g) which was used without further purification.
