Procedure
The title compound was prepared by the method described for 6-oxoheptanoic acid p-toluide (IV, n=4, Y=p-methylanilino) using the following quantities: δ-acetyl-n-valeric acid (2.5 g, 1.75 mmol), N-methylmorpholine (1.9 ml, 17.5 mmol), isobutyl chloroformate (2.25 ml, 17.5 mmol), n-butylamine (1.7 ml, 17.5 mmol), tetrahydrofuran (15 ml). Recrystallization from ethyl acetate/hexanes gave 1.3 g of the desired compound as white needles, which were pure by thin layer chromatography (95:5:3 chloroform/methanol/acetic acid, Rf =0.52) m.p. 53°-54° C.
