Versuchsvorschrift
N-(4-Chloro-3-methyl-5-isothiazolyl)-4-hydroxy-3-nitrophenylacetamide (374 g, 0.114 mol) was hydrogenated at 15 bar over a 3% w/w platinum on carbon catalyst (15 g) in N,N-dimethylformamide (180 ml). Once the reduction was complete, the catalyst was removed by filtration and the filtrate was evaporated in vacuo to give N-(4-chloro-3-methyl-5-isothiazolyl)-3-amino-4-hydroxyphenylacetamide (26.8 g) as a pale brown solid, which used without further purification in the next step.
