A flask containing 3-bromopyruvic acid (317 mg, 1.901 mmol) was put under nitrogen atmosphere. 2-(tert-butyldiphenylsilyloxy)propanethioamide (653 mg, 1.901 mmol) was dissolved in dry THF (8 ml) and added through a septum. The following mixture was refluxed for two hours and then allowed to cool to RT. The solvent was evaporated and extracted with DCM/water and the combined organic phases were evaporated. 1H-NMR (400 MHz; DMSO-d6): δ 1.07 (s, 9H), 1.35 (d, 3H), 5.14 (q, 1H), 7.39-7.54 (m, 2H), 7.57-7.61 (m, 2H), 7.26-7.69 (m, 2H), 8.38 (s, 1H).
