The dinitro precursor was prepared by reacting 2-chloro-4-methoxyphenol (Aldrich Chemical Co., Milwaukee, Wis.) as the potassium 2-chloro-4-methoxyphenolate with methyl 4-chloro-3,5-dinitrobenzoate, as described in Example 1.2.1. The methyl 3,5-dinitro-4-(2'-chloro-4'-methoxyphenoxy)benzoate product (66% yield) was crystallized from ethanol to give orange crystals. Melting point: 116°-119° C.
