Ketone (I) was converted to the corresponding oxime (II) by treatment with hydroxylamine hydrochloride and pyridine. Subsequent alkylation of the oxime (II) with ethyl 5-bromovalerate (III) in the presence of NaH provided (IV). After desilylation of (IV) by means of tetrabutylammonium fluoride, the liberated alcohol (V) was converted to mesylate (VI). The title compound was then obtained by condensation of mesylate (VI) with the pyridothienotriazolodiazepine derivative (VII).
