Embodiment 1
[0043] Preparation of 2-(2-chlorophenylimino)-5-(4-hydroxy-3-methoxybenzylidene)-1,3-thiazol-4-one
[0044]
[0045] by HCl:H 2 The ratio of O (1:4) is dubbed hydrochloric acid solution. Weigh 11.4g (150mmol) of ammonium thiocyanate and dissolve it in 50mL of hydrochloric acid solution, add 10.5mL (100mmol) of 3-toluidine, heat to 85°C under stirring conditions, the mixture becomes clear, after 12 hours of reaction, TLC monitors the reaction, After the reaction, the mixture was cooled to room temperature, and a viscous oily liquid appeared, which was extracted with ethyl acetate, and the extract was washed with 10% hydrochloric acid solution, saturated sodium chloride solution, and water successively, and the solvent was evaporated off the extract under reduced pressure to obtain 2-Tolylthiourea.
[0046] Add 996mg (6.0mmol) of 2-tolylthiourea and 2479mg (30mmol) of anhydrous sodium acetate into 20mL of ethanol, add 1.28mL (12mmol) of ethyl chloroacetate under stirring co...
