YieldReaction ConditionsOperation in experiment
92% With carbon tetrabromide; triethylamine; In acetonitrile; at 20℃; for 2h; General procedure: To a mixture of ketone (0.5 mmol), thiourea (0.5 mmol), and triethylamine (0.5 mmol) in acetonitrile (3 mL) was added carbon tetrabromide (0.5 mmol) in a round bottom flask at room temperature and the reaction mixture was stirred for 2-6 h. After completion of the reaction (monitored by TLC), water (5 mL) was added and the mixture was extracted with EtOAc (3*5 mL). The combined organic phase was dried over MgSO4, filtered, and evaporated under reduced pressure to give the crude product. The resulting product was purified by silica gel column chromatography using a gradient mixture of hexane/ethyl acetate as eluent to afford an analytically pure sample of 3.
With copper(ll) bromide; In water; ethyl acetate; for 3h;Reflux; To a stirred mixture of solvent (6 mL), aqueous ammonia(2.2 mmol, 25%) and dithiocarbamic acid salt 1 (1 mmol), CuBr2 (0.5 mmol) was added slowly, and the reaction mixture was stirred at room temperature for 3 h, thioureas (2) were generated in situ. During this period, a black precipitate was observed and settled at the bottom of the roundbottom flask. The reaction mixture was transferred into centrifuged tubes and the mixture was centrifuged for 10 min by using a centrifugation machine. The black solid settled in the bottom of the centrifuge tubes. Excess ammonia was removed by heating the reaction mixture on a hot-waterbath (50 C) for 10 min. Then CuBr2 (2.2 mmol) and ketone (3, 1.1 mmol) was added and continue reflux. The progress of the reaction was investigated by TLC (2% ethyl acetate in hexane). After finishing the reaction, the reaction mixture was filtered at 50 C and the filter was extracted with ethylacetate (220 mL). The ethyl acetate layer was washed witha saturated solution of NaHCO3 (5 mL), dried over anhydrous Na2SO4, concentrated under reduced pressure, and purified over a silica-gel column (hexane - EtOAc, 9:1:) to give 2-Aminothiazoles 4a-4m.

YieldReaction ConditionsOperation in experiment
76% With triethylamine; In ethanol;Reflux; 25 mL solanes were added with 1 mmol of N-(4-methoxyphenyl) thiourea.1.05 mmol alpha-bromoacetophenone,10 mL of ethanol was added to dissolve, and then 1.5 mmoL of triethylamine was added and refluxed.After TLC tracks the reaction,The temperature of the reaction solution was lowered to room temperature, and the solvent was distilled off under reduced pressure.Column chromatography of the residue (eluent: petroleum ether-ethyl acetate) yields the target compound,It is a white solid with a yield of 76%.
