REFERENCE EXAMPLE 25 Methanesulphonyl chloride (12.2 ml) was added to a stirred, cooled solution of methyl 2-amino-4-methylbenzoate (103 g) and triethylamine (19.5 ml) in dichlorotuethane while maintaining the temperatare below 0 C. The mixture was stirred at room temperature for 4 hours. Hydrochloric acid solution (2M) was added and the layers were separated. The organic layer was washed with water, dried (magnesium sulphate) and filtered. The filtrate was evaporated to dryness to give a mixture of methyl 4-methyl-2-[N,N-bis(methylsulphonyl)amino]benzoate and methyl 4-methyl-2-(N-methylsulphonylamino)benzoate (18.26 g) as a yellow solid which was not further purified.

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
