Chloroacetyl chloride → HCID 22034146, compound

Participants

Reaction Steps

Treat a solution of 3-(2,4-dichlorophenyl)-2,5-dimethylimidazolo[5,4-b]pyridin-7-ylamine (0.2 g, 0.65 mmol), and N,N-diisopropylethylamine, (0.12 mL, 0.72 mmol) in 1,2-dichloroethane (10 mL) with chloroacetyl chloride (0.06 mL, 30.72 mmol). Heat the solution to reflux for 2 h, cool to ambient temperature, and pour into an aqueous potassium carbonate solution. Extract the resulting mixture with CH2Cl2 and wash with saturated aq NaCl. Separate the organic layer, dry over Na2SO4, filter, and concentrate. Purify by preparative TLC (5% methanol in CH2Cl2) to obtain the title compound as a yellow solid.
