Toluene → HCID 17989271, compound

Participants

Reaction Steps

300 mg (0.813 mmol) of 4-(5-bromo-2-methoxyphenyl)-2-hydroxy-4-methyl-2-(trifluoromethyl)pentanal is mixed in 1.19 ml of glacial acetic acid with 108.2 mg (0.813 mmol) of 4-aminoindazole, and it is stirred for four days at room temperature. The batch is spun in until a dry state is reached, and the residue is drawn off three times with toluene. Chromatography on silica gel (mobile solvent ethyl acetate/hexane) yields 352.5 mg (89.5%) of the desired imine (together with the imine of the Desbrom compound).
