    • General procedure to form amino acid-substituted thiocarbazates: Boc-protected amino acid hydrazide (1.0 mmol, 1.0 equiv) was added to a 25-mL round-bottomed flask followed by a solution of KOH in 95% EtOH (0.25 M, 4.4 mL, 1.1 equiv). After stirring for 5 min at 23 °C, a balloon of carbonyl sulfide gas was attached to the flask. The flask was purged with the gas (5 s) and a full balloon was reattached. The reaction was stirred for 15 h at 23 °C. After stirring overnight, the α-bromo anilide (1.1 mmol, 1.1 equiv) was added in one portion and the reaction was monitored by LC-MS. The α-bromo anilides were typically consumed within 20-60 min, and the reaction mixture was filtered, using a Büchner funnel. The filtrate was concentrated on a rotatory evaporator and purified by preparative reverse-phase HPLC.
