Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 87-63-8, name is 2-Chloro-6-methylaniline, A new synthetic method of this compound is introduced below., Product Details of 87-63-8
Ethyl vinyl ether compound of formula-5 (500 gm) was slowly added to oxalyl chloride compound of formula-4 (670 ml) at 10-15C. Raised the temperature of the reaction mixture to 25-30C and stirred for 12 hours at the same temperature. Heated the reaction mixture to 120- 125C and stirred for 90 minutes at the same temperature. Cooled the reaction mixture to 30-35 C and (E)-3-ethoxyacryloyl chloride compound of formula-7 was collected by fractional distillation. Added tetrahydrofuran (1160 ml) to the obtained compound of formula-7 and cooled the reaction mixture to 10-15C. Slowly added a solution of 2-methyl-6-chloroaniline compound of formula-9 (290 gm), pyridine (248ml) & tetrahydrofuran (1160 ml) to the reaction mixture at same temperature. Raised the temperature of the reaction mixture to 25-30C and stirred the reaction mixture for 4 hours at the same temperature. Cooled the reaction mixture to 5-10C and acidified the reaction mixture using aqueous HC1 solution. Water and ethyl acetate were added to the reaction mixture and stirred for 10 minutes. Separated the both aqueous & organic layers and extracted the aqueous layer with ethyl acetate. Washed the total organic layer with aqueous sodium bicarbonate solution followed by with water. Distilled off the solvent completely from the organic layer under reduced pressure. Ethyl acetate was added to the obtained compound at 25-30C and cooled the reaction mixture to 0-5C. Stirred the reaction mixture for 2 hours at the same temperature. Filtered the precipitated solid, washed with chilled ethyl acetate and dried the material to get the title compound. Yield: 300 gm; M.R.: 160-164C; HPLC Purity: 99.66%.
The synthetic route of 87-63-8 has been constantly updated, and we look forward to future research findings.
