Application of 7357-70-2, A common heterocyclic compound, 7357-70-2, name is 2-Cyanothioacetamide, molecular formula is C3H4N2S, its 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.
2-(4-phenylthiazol-2-yl)acetonitrile A mixture of 2-bromoacetophenone (1 .0 g, 5 mmol) and 2- cyanothioacetamide (0.5 g, 10 mmol) in ethanol (25 mL) was heated to 80C for 4 h. The reaction mixture was cooled to room temperature and poured into an aqueous ammonia solution (final pH was >7). The mixture was then extracted with ethyl acetate (100 mL x 3) and the organic layers were washed with H2O and brine. The organic layers were dried over anhydrous magnesium sulfate, filtered, and concentrate in vacuo. The crude product was purified by flash column chromatography, eluting with 0-30% ethyl acetate and petroleum benzene, afforded 2-(4-phenylthiazol-2-yl)acetonitrile (0.69 g, yield 70%) as a yellow solid.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
