YieldReaction ConditionsOperation in experiment
70% With potassium carbonate; In acetonitrile; at 0 - 20℃; for 8h; (1): Synthesis of N1-((2-chlorothiazol-5-yl)methyl)ethane-1,2-diamine To a stirred solution of 0.03mol of potassium carbonate and 10ml (0.15mol) of ethylenediamine in a 50ml of flask placed in an ice bath, 0.03mol of <strong>[105827-91-6]2-chloro-5-(chloromethyl)thiazole</strong> dissolved in 15ml of acetonitrile was added dropwise and slowly. After addition, the ice bath was removed and then the mixture was stirred for 8 hours at room temperature. After the reaction was stopped, a large amount of water was added to dissolve potassium carbonate and ethylenediamine, and the mixture was extracted with dichlormethane. The lower organic phase was collected, dried, and evaporated to dryness. The obtained product was yellow oily liquid in 70% yield. GC MS (m/s) 191 (21) M+, 132(100).

78% In ethanol for 8h; Reflux;
56% With acetic acid In ethanol at 80 - 90℃; for 4h; Heating / reflux; 7.2 (2): Synthesis of 1-((2-chlorothiazol-5-yl)methyl)-2-(nitromethylene)-1-imidazolidine 2.5g (0.0178mol) of 1,1-dimethylthio-2-nitroethene, 3.3g (0.0178mol) of N1-((2-chlorothiazol-5-yl)methyl)ethane-1,2-diamine were dissolved in 15ml of ethanol. The resulting mixture was refluxed at 80-90 °C for 4 hours. The mixture was then cooled to educe solid, concentrated, filtrated and dried to give a light yellow powder in 56% yield. GC MS(m/s) 226 (24), 132(100), 77(9).
