Procedure
To a stirred solution of (R)-tert-butyl 1-thioxo-1-(2,2,2-trifluoroethylamino)propan-2-ylcarbamate (200 mg, 0.69 mmol) in CH2Cl2 (5 mL) was added TFA (0.5 mL) dropwise and the reaction mixture was stirred for 18 h. The volatiles were evaporated and the residue was triturated with pentane to give the title compound as colorless gum, which was taken to next step without further purification (200 mg): 1H NMR (300 MHz, DMSO-d6) δ 10.99 (bs, 1H), 8.23 (bs, 2H), 4.62-4.55 (m, 2H), 4.23-4.19 (m, 1H), 1.43 (d, J=8.4 Hz, 3H); ESIMS m/z 186.2 ([M+H]+); IR (thin film) 3445, 2967, 1168 cm−1.
