Methylhydrazine → 3-({1-[bis(4-chlorophenyl)methyl]-azetidin-3-ylidene}methanesulfonylmethyl)benzoic acid N'methylhydrazide

Participants

Reaction Steps

The operation is carried out under the conditions described in Example 124 starting with 150 mg of activated 3-({1-[bis(4-chlorophenyl)methyl]azetidin-3-ylidene}methanesulfonylmethyl)benzoic acid on TFP resin (165 μM) and 0.0141 cm3 of methylhydrazine. 42 mg of 3-({1-[bis(4-chlorophenyl)methyl]azetidin-3-ylidene}methanesulfonylmethyl)benzoic acid N′methylhydrazide are thus obtained in the form of a pale yellow foam [1H NMR spectrum (400 MHz, (CD3)2SO-d6, δ in ppm): 2.96 (s, 3H), 3.18 (broad s, 3H), 3.83 (mt, 2H), 4.22 (mt, 2H), 4.80 (broad s, 2H), from 7.35 to 7.65 (mt, 12H)].
