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.
