This compound has been obtained by two similar ways: 1. By condensation of the benzophenone derivative (I) with O-(1-methylpiperidin-4-yl)hydroxylamine by means of K2CO3 in propanol. 2. The reaction of benzophenone derivative (I) with hydroxylamine by means of K2CO3 in propanol gives the corresponding oxime (III), which is finally alkylated with 4-chloro-1-methylpiperidine (IV) by means of NaH in DMF.
