合成路线1
1) The reaction of phenol (I) with epichlorohydrin (II) gives 1,2-epoxy-3-phenoxypropane (III), which is treated with isopropylamine (IV) to afford 3-(isopropylamino)-1-phenoxy-2-propanol (V). Cyclization of (V) with diethyl carbonate (VI) yields 3-isopropyl-5-(phenoxymethyloxazolidin-2-one) (VII), which is chloromethylated with formaldehyde - HCl giving 3-isopropyl-5-(4-chloromethylphenoxymethyl)oxazolidin-2-one (VIII). Etherification of (VIII) with ethylene glycol monoisopropyl ether (IX) yields the corresponding ether (XI), which is finally deprotected by alkaline hydrolysis.

合成路线2
The condensation of 4-hydroxybenzyl alcohol (I) with 2-isopropoxyethanol (II) by heating at 150 C gives the corresponding benzyl ether (III), which is condensed with epichlorohydrin (IV) to yield the adduct (V). Finally, this compound is treated with isopropylamine in ethanol.
