Reaction of 3-(4-hydroxyphenyl)propionic acid (I) with the chiral dioxolanylmethyl chloride (II) afforded the corresponding dioxolanylmethyl ester (III). The phenolic hydroxyl group of (III) was then alkylated with (S)-bromohydrin (IV) to produce the intermediate (V).

Morpholine (VI) was treated with carbonyl diimidazole (VII), and the resulting imidazolide (VIII) was further condensed with ethylenediamine (IX) to give urea (X). Reaction of epoxide (V) with amine (X) furnished the title compound.
