The acid chloride of 4-carboxybenzaldehyde (7.0 g, 46.5 mmol) was prepared in the same manner as in Example 29 using thionyl chloride (3.5 mL) and dimethylformamide (0.34 mL) in benzene (250 mL). The amide was prepared from the acid chloride in the same manner and using the same workup procedure as in Example 29 using N-cyclohexyl-N-cyclopentyl amine (15.6 g, 93.1 mmol) in THF (150 mL) at 0° C. The crude product was suitable for use without further purification.
