Versuchsvorschrift

Azetidine Ae (HCl salt) (0.2 g, 2 mmol) was dissolved in ethyl acetate (8 mL). Triethylamine (0.3 mL, 2 mmol) and 3-(chlorosulfonyl)-4-(methylamino)benzoic acid (1.2, 0.1 g, 0.5 mmol) were added. The reaction was left to stir for 4 hours, then extracted with 0.5 M HCl, washed with water and brine, and dried over magnesium sulfate. The ethyl acetate was evaporated and 3-(azetidin-1-ylsulfonyl)-4-(methylamino)-benzoic acid (1.3.Ae) was obtained (0.08 g, 60% yield). MS analysis (m−1)=269.
