Benzenesulfonyl chloride → HCID 22033525, compound

Participants

Reaction Steps

Benzenesulfonyl chloride (0.24 mL; 1.9 mmol) was added to a stirred solution of amino-3-[2-(4-cyanophenyl)ethoxy]-2-methylbenzene (0.42 g; 1.7 mmol; from step (iii) above) in dry pyridine (20 mL) under nitrogen. The reaction was left overnight at room temperature. After evaporation of the solvent the residue was partitioned between 10% aqueous HCl and EtOAc. The organic layer was washed with brine, dried (MgSO4) and the solvent removed in vacuo. Purification by flash chromatography afforded 0.47 g (72%) of the sub-title compound.
