実験手順
Using the general method of Compound 76, 4'-octyloxy-4-biphenylcarboxylic acid (3.26 g, 10 mmole) was converted to the isocyanate then reacted with N-(1-ethylpropyl)hydroxylamine (1.4 g, 13.5 mmole) to provide 2.0 g of the desired product as a light tan crystalline solid, m.p. 151°-152.5° C. Analysis: Calculated for C26H38N2O3 : %C, 73.20; %H, 8.98; %N, 6.57; Found: %C, 73.19; %H, 9.01; %N, 6.50.
