The condensation of 3-acetyl-4-hydroxyaniline (I) with N,N-diethylcarbamoyl chloride (II) in pyridine gives the urea (II), which is treated with epichlorohydrin (IV) and NaOH to yield N-[3-acetyl-4-(2,3-epoxypropoxy)phenyl]-N',N'-diethylurea (V). Finally, the epoxy ring of (V) is opened with tert-butylamine (VI).
