Adding a certain compound to certain chemical reactions, such as: 52867-42-2, name is Methyl 2-methyl-5-oxo-2,5-dihydro-1H-pyrazole-3-carboxylate, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 52867-42-2, Computed Properties of C6H8N2O3<\/a><\/p>\n

To a stirred suspension of methyl 5-hydroxy-2-methyl-pyrazole-3-carboxylate (3.00 g, 19.0 mmol) and K2CO3 (2.90 g, 21.0 mmol) in DMF (19 mL) at room temperature was added iodoethane (1.71 mL, 21.0 mmol) and the reaction mixture stirred at 50 C for 16 h. The reaction mixture was diluted with water (190 mL) and the aqueous layer extracted with ethyl acetate (3 x 100 mL). The combined organic layers were washed with water (2 x 100 mL), passed through a phase separator and concentrated in vacuo. The crude material was purified by flash chromatography [EtOAc\/isohexanes (0-50%)] to afford the title compound (3.33 g, 94% Yield) as a colourless oil. 6H (300 MHz, d-Chloroform) 6.17 (s, 1H), 4.16 (q, J = 7.1 Hz, 2H), 4.03 (s, 3H), 3.86 (s, 3H), 1.38 (t, J = 7.1 Hz, 3H).<\/p>\n
