Pyridine → HCID 57845324, compound

Participants

Reaction Steps

16 μL (0.20 mmol) of thionyl chloride was added at RT to a solution of 50 mg (0.13 mmol) of {6-[5-(4-chlorophenyl)pyridin-2-ylethynyl]-4-methylquinolin-2-yl}methanol and 52 μL (0.65 mmol) of pyridine in 3 mL of DCM and the mixture was stirred for 2 hours at RT. The reaction mixture was diluted with DCM, and the organic phase was washed with saturated aqueous sodium bicarbonate solution, dried over magnesium sulfate, and evaporated down in vacuo. The residue was taken up in 3 mL of DMF, combined with 60 μL (0.51 mmol) of 4-methylpiperidine and stirred for 16 hours at RT. The reaction mixture was evaporated down in vacuo, diluted with DCM, and the organic phase was washed with saturated aqueous sodium bicarbonate solution, dried over magnesium sulfate and evaporated down in vacuo. The crude product was purified by column chromatography (silica gel, gradient DCM/MeOH/sat. aqueous ammonia 100:0:0 95:5:0.5) and HPLC-MS (Zorbax Bonus C18 amide-phase 5 μm, gradient 0.15% formic acid in water/acetonitrile 10/90→90/10 v/v). Yield: 4 mg (7% of theoretical); C30H28ClN3 (M=466.016); calc.: molpeak (M+H)+: 466/468 (Cl); found: molpeak (M+H)+: 466/468 (Cl); Rf value: 0.38 (silica gel, DCM/MeOH/sat. aqueous ammonia 9:1:0.1).
