실험 절차

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 2-methylbutylamine. 49 mg of 3-({1-[bis(4-chlorophenyl)methyl]azetidin-3-ylidene}methanesulfonylmethyl)-N-(2-methylbutyl)benzamide are thus obtained [1H NMR spectrum (400 MHz, (CD3)2SO-d6, δ in ppm): from 0.80 to 0.95 (mt, 6H), from 1.05 to 120 (mt, 1H), 1.41 (mt, 1H), 1.64 (mt, 1H), 2.98 (s, 3H), 3.06 (mt, 1H), 3.19 (mt, 1H), 3.81 (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 7.35 to 7.60 (mt, 2H), 7.84 (broad s, 1H), 7.87 (broad d, J=8 Hz, 1H), 8.49 (t, J=5.5 Hz, 1H)].
