Ethyl 2, 4, 4'-trinitrodiphenylacetate (VI) was obtained by condensation of methyl 4- nitrophenylacetate and 2, 4-dinitrobromobenzene in the presence of sodium in ethanol. Contrary to expectations the same reaction carried out with sodium dissolved in methanol did not lead to the methyl ester, but furnished mainly starting material. In order to prepare the methyl ester, VI was hydrolyzed to the acid which, when'treated with diazomethane, led to ...
