1-Propanesulfonyl chloride → Propane-1-Sulfonic Acid Cyclopropyl Amide

Participants

Reaction Steps

To a solution of cyclopropylamine (1.2 ml, 17.5 mmol) in 100 ml CH2Cl2 and DMAP (2.4 g, 17.5 mmol) was added dropwise a solution of propane-1-sulfonyl chloride (2.3 ml, 19.2 mmol) in 50 ml CH2Cl2. The resulting mixture was stirred at room temperature over night and diluted with 50 ml of CH2Cl2. The mixture was extracted subsequently with water, 1 M HCl, and brine, tried over Na2SO4, filtered and the solvent evaporated to obtain 2.8 g of product (oil) which was used in the next step without further purification.
