To tert-butyl (2S)-4-hydroxy-4-methyl-2-(propan-2-yl)pyrrolidine-1-carboxylate (532.2 mg, 2.18 mmol) dissolved in DCM (5.5 mL) was added TFA (1.8 mL). The mixture was stirred for 16 hours. The mixture was concentrated to give (5S)-3-methyl-5-(propan-2-yl)pyrrolidin-3-ol as a TFA salt. 1H NMR (500 MHz, CDCl3) δ 3.76 (s, 1H), 3.49-3.34 (m, 2H), 2.29-2.17 (m, 1H), 2.06-1.95 (m, 2H), 1.51 (s, 3H), 1.07-0.97 (m, 7H).
