Abstract

The central ring of the title compound, C28H32N2O3, exists in a chair conformation with an equatorial disposition of all the alkyl and aryl groups on the heterocycle. The para-anisyl groups on both sides of the secondary amino group are oriented at an angle of 54.75 (4)° with respect to each other. The oxime derivative exists as an E isomer with the methyl substitution on one of the active methyl­ene centers of the mol­ecule. The crystal packing features weak C—H⋯O inter­actions.
