The reduction of diethyl 3-(methoxymethoxy)glutarate (I) with LiAlH4 in THF gives 3-

(methoxymethoxy)pentane-1,5-diol (II), which is treated with Ts-OH and TEA in THF to

yield the disulfonate (III). The condensation of (III) with 5-ethoxyindolin-2-one

(IV) by means of tBu-OK in THF affords the spiro compound (V), which is deprotected

with HCl in methanol to afford the spiranic alcohol (VI). The oxidation of (VI) with

pyridinium chlorochromate (PCC) over Al2O3 provides the spiranic cyclohexanone (VII),

which is treated with 2-chloroethanol (VIII) and Ms-OH in toluene to give the ketal

(IX). The reaction of (IX) with zinc borohydride and trimethylsilyl chloride in ethyl

ether/dichloromethane yields the 2-chloroethoxy derivative (X), which is condensed

with 4-(N-tert-butylcarbamoyl)-2-methoxybenzenesulfonyl chloride (XI) by means of

tBu-OK in THF to afford the adduct (XII). Finally, the target compound is obtained by

condensation of (XII) with morpholine (XIII) by means of NaI in DMF, followed by

treatment with fumaric acid.
