2-Propanethiol → 5-Nitro-2-(propan-2-ylsulfanyl)benzoic acid

Participants

Reaction Steps

Isopropylthiol (3.06 mL, 32.8 mmol) was added to a solution of 2-fluoro-5-nitrobenzoic acid (5.06 g, 27.3 mmol) and triethylamine (8.4 mL, 60.3 mmol) in DMF (86 mL). The reaction mixture was stirred overnight at rt and then most of the DMF was removed in vacuo. The residual solution was poured into ice water (500 mL) and the resulting yellow solid was isolated by filtration to give 16A (6.5 g, 100%).
