Versuchsvorschrift

1.13 g (7.48 mmol) of methyl 4-aminobenzoate was dissolved in 20 mL of anhydrous DCM and 1.97 g (17.19 mmol) of mesyl chloride was added at 4 deg C., followed by the 2.22 g (17.19 mmol) of the diethylisopropylamine. Reaction was carried out overnight at room temperature resulting methyl 4-[(methylsulfonyl)amino]benzoate, which was used in the next step without additional purification.
