Versuchsvorschrift

To a solution of 2-(methylthio)-6-nitrobenzonitrile (Example 104c) (1.5 g, 7.73 mmol) in EtOH (150 ml)/THF (50 ml)/EtOAc (50 ml) was added 200 mg of 10% Pd/C. The reaction mixture was hydrogenated on part shaker overnight. After the filtration, the filtered solution was dried down under vacuum, and the residue was purified by chromatography on silica gel eluting with EtOAc/Hexane to give the title compound (79%). 1H NMR (400 MHz, CDCl3) δ 2.51 (s, 3H), 4.47 (s, 2H), 6.53-6.51 (m, 1H), 6.58 (d, J=8.0 Hz, 1H), 7.27-7.21 (m, 1H).
