Procedure

To a solution of 5 g (21 mmol) of 2-(azetidine-1-sulfonyl)-2-methyl-propionic acid ethyl ester in THF (200 mL) at room temperature are added 8.2 g (64 mmol) of potassium trimethylsilanolate. The reaction is stirred for 1 h. The mixture is diluted with 1M aqueous HCl solution (50 mL) and extracted with DCM (250 mL). The organic phase is dried over Na2SO4, filtered and the filtrate is concentrated under reduced pressure to provide 4.1 g of 2-(azetidine-1-sulfonyl)-2-methyl-propionic acid as a white solid. Yield: 94%, ES-MS: m/z 208 [M+H].
