Synthesis
Step 2: 5-Methyl-2-nitrobenzamide (15.0 g, 83.3 mmol) was dissolved in methanol (300 mL) and 10% palladium carbon catalyst (2.50 g) was added. The reaction was stirred for 12 hours under hydrogen atmosphere (1 atmosphere) and room temperature. After completion of the reaction, the insoluble material was removed by filtration and the filtrate was concentrated to afford 2-amino-5-methylbenzamide (12.4 g, 99% yield) in white powder form.
