Participants

Reaction Steps

2-Methyl-2-(3,3,3-trifluoro-propane-1-sulfonyl)-propionic acid ethyl ester (1.3 g, 4.63 mmol) is dissolved in THF/water (14 mL, 4:1 ratio) and LiOH (0.2 g, 9.27 mmol, 2 eq.) is added. The mixture is stirred for 18 h at room temperature, then concentrated under reduced pressure to remove the organic solvent. The aqueous residue is further diluted with water, washed with DCM and then acidified to pH ˜2 and extracted with DCM. The combined acidic organic extracts are concentrated to afford 0.97 g of title compound. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.72 (3H, s), 2.64-2.81 (2H, m), 3.46-3.6 (2H, m)
