関与物質

反応手順

Methylamine (4.5 ml of 2.0 M solution in THF) was added to a stirred solution of 2-chloro-1,3-dinitrobenzene (0.90 g, 4.4 mmol) in 40 ml of THF and the mixture was stirred for 30 min. The reaction was quenched by the addition of water and ether. The aqueous layer was separated and extracted twice with ether. The combined organic extracts were washed with saturated NaHCO3, brine and dried over magnesium sulfate. Filtration, removal of solvent and purification of residue via Biotage chromatography eluting with 20% ethyl acetate/dichloromethane to gave 0.80 g (91%) of product.
