Reaction Steps

A 2 liter Parr Bottle was charged with 11.6 grams (55 mmol) methyl-2-methoxy-5-nitrobenzoate, 450 mL of methanol and 150 mL of tetrahydrofuran (THF). Platinum oxide was added (460 mg) and the mixture was hydrogenated under 45 psi hydrogen for 1 hour. The reaction mixture was filtered through Celite® (diatomaceous earth) and evaporated. The reaction mixture was diluted with 500 mL of methylene chloride, and then washed with water and brine. The organic phase was dried and evaporated (9.9 grams). This material was used without further purification.
