Phenylmethanesulfonyl chloride → HCID 68292276, compound

Participants

Reaction Steps

While cooling with ice, 5.00 g of phenylmethanesulfonyl chloride were initially charged in 40 ml of dichloromethane, and a solution of 8.04 ml of 2,4-dimethoxybenzylamine in 10 ml of dichloromethane was slowly added dropwise. For improved stirrability, a further 25 ml of dichloromethane were added, and the reaction mixture was allowed to come to room temperature. After stirring for 2 hours, the reaction mixture was washed with 100 ml of water, with 100 ml of 0.2 N aqueous hydrochloric acid, with 100 ml of saturated aqueous sodium hydrogencarbonate solution and finally once more with 100 ml of water. The organic phase was dried over Na2SO4, concentrated by rotary evaporation and dried under high vacuum. The residue (8.42 g) was used in the next reaction without further purification.
