Reaction Steps
To a solution of methyl 3,5-dimethyl-4-nitrobenzoate (10.0 g, 0.0478 mol) in methanol (100 mL), iron powder (15.7 g, 0.2869 mol) and 37% HCl (1.72 g, 0.0478 mol) is added at 0° C. The reaction is heated at 80° C. for 16 hours. The mixture is cooled to room temperature and filtered through Celite™ bed and washed with methanol followed by evaporation of filtrate to dryness to afford the title compound as a brown solid (7.8 g, 99%). Mass spectrum (m/z): 180.2 (M+1).
