3-({[tert-Butyl(diphenyl)silyl]oxy}methyl)-1-(2-chloro-4-nitrophenyl)pyridin-2(1H)-one → 1-(4-Amino-2-chlorophenyl)-3-({[tert-butyl(diphenyl)silyl]oxy}methyl)pyridin-2(1H)-one

Reaction Steps

800 mg (1.54 mmol) of the compound from Example 4A are dissolved in 48 ml of THF. 50 mg (0.05 mmol) of palladium on carbon are then added, and the mixture is hydrogenated at RT in a hydrogen atmosphere under atmospheric pressure. The mixture is then filtered, the filter cake is washed with THF and the filtrate is freed from the solvent. The reaction product (purity: 95%) is reacted further without further purification.
