Reaction Steps

To a solution of 2,4-dimethoxy-benzylamine hydrochloride (1 eq.) and TEA (2 eq.) in DCM was added dropwise at 0° C. a solution of 3-chloro-propane-1-sulfonyl chloride (1 eq.) in DCM. The reaction was stirred at 20° C. for 20 h. The crude was diluted with DCM, washed twice with water, twice with aqueous HCl (0.1N) and twice with a saturated aqueous solution of NaHCO3. The organic layer was dried over MgSO4, filtered and concentrated under reduced pressure. The crude was purified by chromatography on silica gel (elution with heptane/EtOAc: 100/0 to 20/80) to afford 3-chloro-propane-1-sulfonic acid 2,4-dimethoxy-benzylamide.
