Reaction Steps
To 1-(3-methyl-4-nitro-phenyl)-1H-imidazole (200 mg, 0.98 mmol) and 10% Palladium on carbon (35 mg) was added degassed methanol (3 mL). The suspension was flushed and evacuated with hydrogen/vacuum line. The suspension was allowed to stir at room temperature for 14 h under hydrogen atmosphere (hydrogen balloon). The dark reaction mixture was filtered through a pad of celite and rinsed with methanol. Concentration of the filtrate gave the title compound (166 mg, 98%) which was used for the next step without purification. 1H NMR (300 MHz, DMSO-d6) δ 7.95 (1H, s), 7.48 (1H, s), 7.16 (1H, narrow d, J=2.5 Hz), 7.09 (1H, dd, J=2.5, 8.4 Hz), 7.01 (1H, s), 6.67 (1H, d, J=8.4 Hz), 5.03 (2H, broad s), 2,10 (3H, s).
