Hydrochloric Acid → HCID 3979718, compound

Participants

Reaction Steps

In a 200 ml-three-necked flask, 3.34 g (44.5 mM) of glycine, 0.89 g (22.3 mM) of sodium hydroxide and 16.7 ml of distilled water were placed and mixed. To the solution, 16.7 ml of dioxane was added. To the resultant mixture, a solution of 0.89 g (22.3 mM) of sodium hydroxide in 8.4 ml of distilled water and a solution of 5.00 g (22.2 mM) of 4-hexylbenzoyl chloride in 33.4 ml of dioxane were gradually added simultaneously at -1° to 3° C. by dropping funnels, respectively, followed by stirring for 30 minutes at 1°-2° C. After the reaction, 2.3 ml of concentrated hydrochloric acid was added to the reaction mixture to precipitate a crystal. The crystal was recovered by filtration and washed with water, followed by drying and recrystallization from ethyl acetate to obtain 4.86 g of N-(4-hexylbenzoyl)glycine (Yield: 82.9%).
