Reaction Steps

1-Methyl-2-nitrodibenzothiophene (Method 11; 0.855 g, 3.52 mmol) was stirred in ethanol (50 ml) and EtOAc (50 ml) under an argon atmosphere. 10% Palladium on carbon (0.09 g) was added to the solution and the reaction mixture was stirred under a hydrogen atmosphere at room temperature for 3 h. The mixture was filtered through diatomaceous earth and washed with EtOAc before the filtrate was evaporated in vacuo. The crude product was purified by flash chromatography eluting with 50% DCM/iso-hexane-DCM. Evaporation of the appropriate fractions left the product as a colourless solid. NMR: 8.39 (m, 1H), 7.92 (m, 1H), 7.50 (m,1H), 7.42 (m, 2H), 6.92 (d, 1H), 4.98 (brs, 2H), 2.60 (s, 3H); m/z 215.
