Reaktionsschritte
In ethanol (10 ml) and ethyl acetate (60 ml) was dissolved 4-methylphenyl 4-nitrobenzyl sulfone (0.5 g; G. Bram et al., Synthesis, 1987, 56-59). To the mixture was added 10% palladium on carbon (0.05 g) and catalytic hydrogenation was carried out at room temperature over night. The catalyst was filtered off, and the solvent was evaporated to give 4-aminobenzyl 4-methylphenyl sulfone (0.4 g) as colorless crystals.
