Procedure

2 cm3 of dichloromethane and then 11 mg of methyl isothiocyanate are successively added, at a temperature close to 20° C., to 54.25 mg of 1-[3-({1-[bis-(4-chlorophenyl)methyl]azetidin-3-ylidene}methanesulfonylmethyl)phenyl]piperazine. After stirring for 6 hours at a temperature close to 20° C., 0.05 cm3 of water is added to the reaction mixture. After stirring for 15 minutes at the same temperature, the reaction medium is dried over magnesium sulfate, filtered and concentrated to dryness under reduced pressure (1 kPa) at a temperature close to 40° C. 61 mg of 4-[3-({1-[bis-(4-chlorophenyl)methyl]azetidin-3-ylidene}methanesulfonylmethyl)phenyl]piperazine-1-carbothioic acid N-methylamide are thus obtained in the form of a beige lacquer [1H NMR spectrum (400 MHz, CDCl3), δ in ppm): 2.77 (s, 3H), 3.20 (d, J=5 Hz, 3H), 3.32 (t, J=5.5 Hz, 4H), 3.81 (mt, 2H), 4.00 (t, J=5.5 Hz, 4H), 4.33 (mt, 2H), 4.49 (s, 1H), 5.63 (broad q, J=5 Hz, 1H), 6.80 (d, J=8 Hz, 1H), 6.85 (dd, J=8 and 2.5 Hz, 1H), 6.94 (broad s, 1H), from 7.20 to 7.30 (mt, 5H), 7.32 (d, J=8 Hz, 4H)].
