Methanol → 4,5-Dimethoxy-2-(3,3,5,5-tetramethylcyclohexyl)phenylamine

Participants

Reaction Steps

A mixture of 4,5-dimethoxy-1-nitro-2-(3,3,5,5-tetramethylcyclohex-1-enyl)benzene (1.0 g, 3.13 mmol) produced in Example (87b), 10% palladium on carbon (500 mg, wet), methanol (8 mL) and tetrahydrofuran (2 mL) was stirred for 13 hours at room temperature and atmospheric pressure under a hydrogen atmosphere. The mixture was filtered through Celite to remove the catalyst, and the filtrate was concentrated. A crude product of the title compound was obtained as a yellow oil. The crude product was used without purification for the following reaction.
