Related Products of 40545-33-3,Some common heterocyclic compound, 40545-33-3, name is 2-Amino-5-methylbenzamide, molecular formula is C8H10N2O, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Step 3 To a solution of 2-amino-5-methylbenzamide (5.80 g, 38.6 mmol) and triethylamine (4.69 g, 46.3 mmol) in THF (200 mL) was added dropwise ethyl chloroglyoxylate (5.80 g, 42.5 mmol) under ice-cooling, and the mixture was stirred at room temperature for 3 hr. The reaction mixture was diluted with ethyl acetate, washed with water and saturated brine, dried over sodium sulfate, and concentrated under reduced pressure. The residue was washed with ethanol to give ethyl ((2-(aminocarbonyl)-4-methylphenyl)amino)(oxo)acetate as a white powder (9.83 g, 100%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Amino-5-methylbenzamide, its application will become more common.
