Adding a certain compound to certain chemical reactions, such as: 148550-51-0, Ethyl 2-(methylsulfonyl)pyrimidine-5-carboxylate, 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, Computed Properties of C8H10N2O4S, blongs to pyrimidines compound. Computed Properties of C8H10N2O4S
To a stirred solution of Example 2 (1.87 g, 6.94 mmol) in dry acetonitrile, potassium carbonate (2.87g, 20.8 mmol, spectrochem) and ethyl 2-(methylsulfonyl)pyrimidine-5-carboxylate were added and the resulting mixure was at rt for 12 h. It was filtered through celite and concentrated. Dichloromethane (25 mL) was added and the solution was washed with water, brine and dried over Na2SO4. After evaporation of the solvents, the crude product was purified by flash column chromatography to afford the title compound (white solid). 1H NMR (400 MHz, DMSO-d6): 8.74 (s, 2H), 6.85 (t, J = 7.8 Hz, 2H), 6.75 (d, J = 7.8 Hz, 1H), 5.98 (s, 2H), 4.25 (q, J = 6.8 Hz, 2H), 3.81 (s, 4H), 3.32 (s, 1H), 2.37-2.42 (m, 4H), 1.28 (d, J = 6.6 Hz, 6H). LCMS: (Method A) 385.2 (M+H), Rt. 3.22 min, 98.88percent (Max).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,148550-51-0, Ethyl 2-(methylsulfonyl)pyrimidine-5-carboxylate, and friends who are interested can also refer to it.
