In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 103626-03-5, name is Ethyl 1-methyl-3-oxo-2,3-dihydro-1H-pyrazole-4-carboxylate belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 103626-03-5

Reference Example 37 A mixture of ethyl3-hydroxy-1-methyl-lH-pyrazole-4- carboxylate (25.50 g), benzyl bromide (17.8 ml), potassium carbonate (31.10 g) and N, N-dimethylformamide (250 ml) was stirred overnight at50 C. The reaction mixture was poured into water, and extracted with ethyl acetate. The ethyl acetate layer was washed with dilute hydrochloric acid and then with saturated aqueous sodium chloride solution, dried(MgS04) and concentrated. The residue was subjected to silica gel column chromatography, and ethyl3-benzyloxy-l-methyl-lH- pyrazole-4-carboxylate (31.90 g, yield82%) was obtained as colorless crystals from a fraction eluted with ethyl acetate- hexane (1: 1, volume ratio). The crystals were recrystallized from ethyl acetate-hexane. melting point:66-67 C.
