The operation is carried out under the conditions described in Example 124 starting with 110 mg of activated 3-({1-[bis(4-chlorophenyl)methyl]azetidin-3-ylidene}methanesulfonylmethyl)benzoic acid on TFP resin (121 μM) and 0.023 cm3 of neopentylamine. 69 mg of 3-({1-[bis(4-chlorophenyl)methyl]azetidin-3-ylidene}methanesulfonylmethyl)-N-(2,2-dimethylpropyl)benzamide are thus obtained in the form of a pale yellow powder [1H NMR spectrum (400 MHz, (CD3)2SO-d6, δ in ppm): 0.90 (s, 9H), 2.98 (s, 3H), 3.11 (d, J=6.5 Hz, 2H), 3.82 (mt, 2H), 4.23 (mt, 2H), 4.79 (s, 1H), 7.36 (d, J=8 Hz, 4H), 7.46 (d, J=8 Hz, 4H), from 7.45 to 7.60 (mt, 2H), 7.83 (broad s, 1H), 7.86 (broad d, J=8 Hz, 1H), 8.37 (t, J=6.5 Hz, 1H)].
