Conditions

Procedure

By carrying out the operation according to the procedure of Example 24, but starting with 0.21 g of N-{1-[bis(4-chlorophenyl)methyl]azetidin-3-yl}-phenylsulfonamide, 17 mg of 80% sodium hydride and introducing iodomethane in two portions at an interval of 3 hours. 80 mg of N-{1-[bis(4-chlorophenyl)-methyl]azetidin-3-yl}-N-methylphenylsulfonamide are thus obtained in the form of a white lacquer [1H NMR spectrum (300 MHz, CDCl3, δ in ppm): 2.70 (s: 3H); 3.03 (broad t, J=7.5 Hz: 2H); 3.37 (broad t, J=7.5 Hz: 2H); 3.94 (mt: 1H); 4.28 (s: 1H); from 7.20 to 7.35 (mt: 8H); from 7.45 to 7.65 (mt: 3H); 7.74 (broad d, J=8 Hz: 2H)].
