Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 7357-70-2, name is 2-Cyanothioacetamide, A new synthetic method of this compound is introduced below., Safety of 2-Cyanothioacetamide
To a solution of [CC-CYANOTHIOACETAMIDE] (0.5 g, 5 mmol) in DMF (3 mL) [A-BROMOACETOPHENONE] (1 g, [5] mmol, dissolved in 3 mL of DMF) was slowly added (dropping funnel). Approximately 30min after the addition the mixture was heated to [70C] for 30min, after which the reaction was complete as judged by TLC (SiO2; hexane/AcOEt 8: 2, [RF=0.] 3) The dark solution was poured onto water (50 mL) and extracted with AcOEt (3 x 30 mL). The combined organic phases were dried over [NA2SO4] and concentrated under vacuum. The resultant oily residue was dissolved in EtOH (2 mL) and poured in water (30 mL). After 1 hour stirring at room temperature the formed solid was filtered off, washed with [H20] and dried under vacuum (2 h, [50C] ; 48 h, [25C).] Pure [4-phenylthiazol-2-yl] acetonitrile (3,0. 87 g, 87%) was obtained. Analytical data [‘H-NMR] [(DMSO-D6,] [8)] : 7.9 (bd, 2H); 7.26-7. 5 [(M,] 4H); 4.2 (s, 2H) M. P. = [60C]
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.
