実験手順

N-(2,2-dimethoxyethyl)-4-fluoro-3-methoxyaniline (1.46 g, 6.37 mmol) in dichloromethane (20 ml) was treated with pyridine (0.5 g 6.37 mmol) and methanesulphonyl chloride (766 mg, 6.69 mmol) and the mixture stirred until the reaction was complete by tlc. Aqueous work up and removal of solvent in vacuo gave N-(2,2-dimethoxyethyl)-N-methanesulphonyl-4-fluoro-3-methoxyaniline 1.91 g
