3,4,5-三氯苯甲酰胺

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 3,4,5-trichlorobenzamide (25.0 g, 111 mmol) and potassium 4-chlorothiophenolate (29.0 g, 159 mmol) in dimethylformamide (220 ml) was stirred for 3 days at ambient temperature under nitrogen atmosphere, poured into ice water (2.2 L), and filtered. The solid was washed with water, partially dried under vacuum, suspended in diethyl ether (200 ml), filtered, and washed with diethyl ether (2×75 ml). The residue was triturated with diethyl ether (75 ml), filtered, again triturated with diethyl ether (75 ml), filtered, and dried under vacuum to provide 21.2 g (57%) of 4-(4-chlorophenylthio)-3,5-dichlorobenzamide, m.p. 171°-174° C. filtered The solid was washed with water partially dried under vacuum filtered washed with diethyl ether (2×75 ml) The residue was triturated with diethyl ether (75 ml) filtered again triturated with diethyl ether (75 ml) filtered dried under vacuum

实验步骤: To a solution of 3,4,5-trichlorobenzene carboxamide (25 g) in 220 ml of dry dimethylformamide (DMF), 26 g of 1-naphthalenethiol potassium salt is added and the reaction mixture stirred at room temperature for two days. The reaction mixture is then diluted with water and extracted with methylene chloride. The combined extracts are washed with water, dried with anhydrous magnesium sulfate and concentrated. The product can be purified by chromatography on silica gel. extracted with methylene chloride The combined extracts are washed with water dried with anhydrous magnesium sulfate concentrated The product can be purified by chromatography on silica gel
