Pyridine → N-(2-Chloro-4-fluorosulphonylphenyl)-2-acetoxy-2-methylpropanamide

Participants

Reaction Steps

A solution of 2-chloro-4-fluorosulphonylaniline (2.5 g, 12 mmol), 2-acetoxyisobutyryl chloride (2.35 g, 14 mmol) and pyridine (1.2 ml, 14.5 mmol), in DCM (50 ml) was stirred at ambient temperature for 18 h. The mixture was washed with water, dried and evaporated to dryness. The residue was purified by column chromatography using 25% EtOAc/isohexane and the oily product, the title compound (2.0 g, 5.9 mmol), solidified on standing. MS: 336.
