実験手順

A round bottom flask was charged with methyl 4-chloro-3-(chlorosulfonyl)benzoate (12.0 g, 44.32 mmol) and 1,4-dioxane (100 mL) at 0° C. Cyclopropyl amine (9.31 mL, 137.8 mmol) was added dropwise and the mixture was stirred at that temperature for 3 h. The solvent was removed and the residue was treated with EtOAc. The organic phase was washed with brine, dried, and concentrated to get the title compound (4.5 g, 32% yield).
