Reaction Steps
The title compound was prepared by oxidation of N-(4-ethoxyphenyl)-N-tert-octylamine with m-chloroperoxybenzoic acid in methylene chloride. The amine was synthesized via NaBH4 reduction from the corresponding imine which was acquired by condensation of 4-ethoxybenzaldehyde and tert-octylamine in methanol. The title compound was isolated in 65.0% overall yield as white crystals, m.p. 100.8° C. (Rf=0.33 on silica gel plate using hexanes:EtOAc, 7:3, v/v, as an eluant).
