Reaction Steps
In a 100 ml round-bottom flask fitted with a condenser and drying tube is placed 5-n-decanoylsalicylic acid (1.85 g., 6.7 mmoles), dry chlorobenzene (50 ml), and phosphorous trichloride (0.47 g., 3.4 mmoles). The mixture is then stirred by means of a magnetic stirring bar while the mixture is heated to 60° C. for three hours. The resulting solution is cooled to room temperature and 0.93 g. (6.7 mmoles) of p-nitroaniline is added. The mixture is then heated to 60° C. for three hours, with stirring, and then refluxed for 24 hours. The solvent is removed by vacuum vaporization and the residue is recrystallized from ethanol-water. The crystalline product is triturated with concentrated hydrochloric acid, collected and washed with water. Recrystallization from ethanol-water gives 0.64 grams of 5-n-decanoyl-4'-nitrosalicylanilide, mp 142°-143° C.
