(Cyclopropylmethyl)ammonium chloride → 3-({1-[bis(4-chlorophenyl)methyl]azetidin-3-ylidene}methanesulfonylmethyl)-N-cyclopropylmethylbenzamide

Participants

Reaction Steps

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), 0.026 cm3 of triethylamine and 21 mg of aminomethylcyclopropane hydrochloride. 68 mg of 3-({1-[bis(4-chlorophenyl)methyl]azetidin-3-ylidene}methanesulfonylmethyl)-N-cyclopropylmethylbenzamide are thus obtained in the form of a yellow foam [1H NMR spectrum (400 MHz, (CD3)2SO-d6, δ in ppm): 0.24 (mt, 2H), 0.44 (mt, 2H), 1.03 (mt, 1H), 2.98 (s, 3H), 3.15 (t, J=6 Hz, 2H), 3.82 (mt, 2H), 4.23 (mt, 2H), 4.79 (s, 1H), 7.36 (d, J=8.5 Hz, 4H), 7.46 (d, J=8.5 Hz, 4H), from 7.50 to 7.60 (mt, 2H), 7.86 (broad s, 1H), 7.89 (broad d, J=8 Hz, 1H), 8.64 (t, J=6 Hz, 1H)].
