실험 절차

A mixture of 2-amino-5-methoxybenzoic acid (5.00 g, 29.9 mmol) and urea (5.40 g, 90.0 mmol) was heated to 200° C. for 1 hour. The mixture was cooled to room temperature and diluted with H2O (50 mL), the mixture was filtered off and the precipitate was washed with H2O (10 mL), dried in vacuo to give the product (5.10 g, yield 88%).
