Oxalyl chloride → HCID 86690015, compound

Participants

Reaction Steps

To an anhydrous tetrahydrofuran (5 mL) solution of oxalyl chloride (0.12 mL) was added dropwise an anhydrous tetrahydrofuran (10 mL) solution of N2-(4-methoxyphenyl)naphthalene-1,2-diamine (322 mg, 1.22 mmol) under cooling in an ice-bat. The mixture was stirred under cooling in ice-bath for 30 minutes and at room temperature for one hour. The reaction mixture was poured into a saturated aqueous sodium hydrogen carbonate solution, and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate. The solvent was removed by evaporation under reduced pressure. The obtained solid was filtered. The crude crystal was washed with ethyl acetate and hexane to obtain the titled compound as a slightly off-white crystal (220 mg, yield 56%).
