tert-Butyl mercaptan → HCID 58585855, compound

Participants

Reaction Steps

To the solution of 4-chloro-6-iodo-quinoline-3-carbonitrile (example 14c, 1.0 g, 3.18 mmol) in anhydrous DMF (1 mL) and DIEA (1.67 mL, 9.54 mmol) was added 2-methyl-2-propanethiol (0.72 ul, 6.4 mmol). The mixture was stirred at room temperature for 4 h. The reaction was extracted with methylene chloride (2×100 mL). The combined organic layers were successively washed with water (3×50 mL), dried over sodium sulfate, filtered, and concentrated in vacuo. Flash chromatography (Merck Silica gel 60, 70-230 mesh, 0%-50% ethyl acetate in hexanes in 30 min) afforded 4-tert-butylsulfanyl-6-iodo-quinoline-3-carbonitrile (0.57 g, 48%) as a white solid. LC-MS m/e 369 (MH+).
