3-Chloro-4-fluoroaniline → HCID 9077377, compound

Participants

Reaction Steps

4-Methyl-1,2,3-thiadiazole-5-carboxylic acid (39.6 mg, 0.275 mmol) was suspended in DCM (2.0 mL). Bromotris(pyrrolydino)phosphonium hexafluorophosphate (128 mg, 0.27 mmol) and DIPEA (96 μL, 0.55 mmol) were added and premixed for 5 minutes. 3-Chloro-4-fluoroaniline (40 mg, 0.27 mmol) was added. The solution was stirred for 3 hrs, then purified by silica gel chromatography, (Hex/EA)-eluting at ˜60% EA in hexane to afford the desired product (44 mg). MF=C10H7ClFN3OS; LCMS calculated for C10H8ClFN3OS (M+H)+: m/z=272.0.
