Versuchsvorschrift

At room temperature, 1.00 g of o-tolylmethanesulfonyl chloride was initially charged in 30 ml of dichloromethane, and 1.46 ml of 2,4-dimethoxybenzylamine were added dropwise. The reaction mixture was stirred for 30 minutes. Then the mixture was admixed with 50 ml of water and 50 ml of ethyl acetate, and then the aqueous phase was washed once more with 30 ml of ethyl acetate. The combined organic phases were washed with 1 N aqueous hydrochloric acid, dried over MgSO4 and concentrated by rotary evaporation. The residue (1.42 g) was used in the next reaction without further purification.
