Reference of 63920-73-0, The chemical industry reduces the impact on the environment during synthesis 63920-73-0, name is 2-Amino-4,6-dimethoxybenzamide, I believe this compound will play a more active role in future production and life.
To a solution of 2-amino-4,6-dimethoxy-benzamide (7.50 g, 38.2 mmol) and 3-(2-hydroxy-ethoxy)-5-methoxy-benzaldehyde (7.50 g, 38.2 mmol) in N,N-dimethylacetamide (30 mL) was added NaHSO3 (58.5 wt %, 4.37 g, 42.0 mmol) and p-TSA (0.72 g, 3.8 mmol). The reaction mixture was heated to 115-120 C. for 16 hours, and then cooled to room temperature. N,N-dimethylacetamide was removed under reduced pressure, the residue was diluted with water (50 mL), and the solid was filtered, collected, and mixed with ether (50 mL), then filtered and dried under vacuum, to give 2-[3-(2-hydroxy-ethoxy)-5-methoxy-phenyl]-5,7-dimethoxy-3H-quinazolin-4-one as a white solid. Yield: 10 g (70%).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Amino-4,6-dimethoxybenzamide, other downstream synthetic routes, hurry up and to see.
