실험 절차

A mixture of 4-(2-chloro-4-trifluoromethylphenoxy)-1,2-dinitrobenzene (1.6 g, 4.4 mmol), dimethyl ethylphosphonite (1 ml, 8.8 mmol) and acetonitrile (6 ml) is stirred at room temperature overnight. The reaction mixture is concentrated to dryness, and the residue is purified by preparative thin layer chromatography (silica gel, eluting with 10% ethyl acetate/hexane) to give methyl P-ethyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinate.
