Synthetic Route of 33097-11-9, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.33097-11-9, name is 4,6-Dichloro-2-(methylthio)pyrimidine-5-carbaldehyde, molecular formula is C6H4Cl2N2OS, molecular weight is 223.0798, as common compound, the synthetic route is as follows.
To a solution of pyrimidine (1.55 g, 7.0 mmol) from step (a) in THF (20 mL) was added Et3N (1.5 equiv, 10.5 mmol, 1.5 mL). The solution was then cooled to 00C, followed by dropwise addition of ethyl-2-mercapto -acetate (1 equiv, 0.77 mL). The mixture was stirred for Ih at 00C. After this time, the reaction was concentrated, triturated with hexanes and filtered. The mother liquor was concentrated and subjected to silica gel chromatography (88:12 hexanes/ethyl acetate). Concentration of the desired fractions afforded 1.6g of the desired compound as a white solid (5.2 mmol, 75%). 1H NMR (CDCl3, 300 MHz) delta 10.43 (s, IH), 4.22 (q, 2H, J=7.2 Hz), 3.90 (s, 2H), 2.60 (s, 3H), 1.28 (t, 3H, J=7.2 Hz). CHN CaIcM fOr CiOHi1ClN2O3S2: C, 39.15; H, 3.61; N, 9.13. Found: C, 39.29; H, 3.50; N, 9.05.
Statistics shows that 33097-11-9 is playing an increasingly important role. we look forward to future research findings about 4,6-Dichloro-2-(methylthio)pyrimidine-5-carbaldehyde.
