Procedure
1-Nitro-3,5-bis(trimethylsilyl)benzene (264 mg, 0.99 mmol) was catalytically hydrogenated over 10% Pd-C in 15 ml of benzene at atmospheric pressure for 135 minutes. The catalyst was filtered off and washed with benzene. The filtrate and washings were mixed and evaporated. The residue was purified by column chromatography on silica gel [eluent: methylene chloride-n-hexane (2:1)] to give 224 mg of light tan-colored low melting solid (yield 96%).
