mixing a compound represented by Formula (1), a compound represented by Formula (2), and an oxidizing agent to obtain a hemiaminal compound represented by Formula (3),

OG Complex Work Unit Chemistry
in the formulae, R1 represents a hydrocarbon group which may have a substituent,
the hydrocarbon group has 1 to 30 carbon atoms,
the substituent is a group selected from a substituent group W,
the group selected from the substituent group W may be further substituted with a group selected from the substituent group W,
the substituent group W includes a halogen atom, a heteroaryl group, a cyano group, a hydroxyl group, a carboxyl group, a nitro group, an alkoxy group, an aryloxy group, a silyloxy group, a heterocyclic an oxy group, an acyloxy group, a carbamoyloxy group, an alkoxycarbonyloxy group, an aryloxycarbonyloxy group, an amino group, an ammonio group, an acylamino group, an aminocarbonylamino group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, a sulfamoylamino group, an alkyl or arylsulfonylamino group, a mercapto group, an alkylthio group, an arylthio group, a heterocyclic thio group, a sulfamoyl group, an alkyl or arylsulfinyl group, an alkyl or arylsulfonyl group, an acyl group, an aryloxycarbonyl group, an alkoxycarbonyl group, a carbamoyl group, an aryl or heterocyclic azo group, an imide group, a phosphino group, a phosphinyl group, a phosphinyloxy group, a phosphinylamino group, a phosphono group, a silyl group, a hydrazino group, an ureido group, and a boronic acid group, and
R2 and R3 each independently represent a hydrocarbon group substituted with a halogen atom, a cyano group, a nitro group, an acyl group, an alkyloxycarbonyl group, an aryloxycarbonyl group, an alkylsulfonyl group, an arylsulfonyl group, a dialkylsulfamoyl group, a dialkylamide group, or a heterocyclic group.
