Paragraph 0017; 0019, (2019/08/28)
Provided is a method for preparing an indazole 2-oxides compound, which comprises the step of: performing a cyclization reaction on 2-alkynyl aniline compound and tert-butylnitrite represented by formula (1) in the presence of bis(dibenzylideneacetone) palladium so as to produce an indazole 2-oxides compound, in which, in the formulae (1) and (2), R1 , R2 , R3 and R4 are each hydrogen, halogen or alkyl group; X1 represents an alkyl group, a first chemical structure, a second chemical structure or a third chemical structure where T1 , T2 , T3 , T4 and T5 are each hydrogen, halogen, alkoxy group, or alkyl group; X2 represents hydrogen, cycloalkyl group, alkyl group, alkenyl group, thienyl group, unsubstituted phenyl group, or substituted phenyl group, where the substituent is selected from the group consisting of an alkyl group, an alkoxy group, a halogen, a haloalkyl group, -CN, or -NO2.
