Reaction Steps

0.7 ml of pyridine and then 2.27 g of 3,4-dimethoxybenzenesulfonyl chloride are successively added at room temperature to 1.86 g of 4-chloro-2-(pyridin-2-ylmethyl)aniline in solution in 20 ml of tetrahydrofuran. After 72 hours at room temperature, the reaction medium is taken up in water and extracted with ethyl acetate, the organic phase is dried over anhydrous sodium sulfate and concentrated in order to obtain 2.12 g of the expected product.
