Isodurene or 1,2,3,5-tetramethylbenzene is an

tetramethylbenzene, the other two being prehnitene (1,2,3,4-tetramethylbenzene) and durene (1,2,4,5-tetramethylbenzene).[1]

Preparation

Isoodurene can be prepared from mesitylene, which is converted to mesityl bromide. The latter reacts with magnesium to give the Grignard reagent, which can be alkylated with dimethyl sulfate: [2]

Industrially, isodurene can be isolated from the

trimethylbenzenes.[1]
