N-(3-Aminopropyl)morpholine → 3-({1-[bis(4-chlorophenyl)methyl]azetidin-3-ylidene} methanesulfonylmethyl)-N-(3-morpholin-4-ylpropyl)benzamide

Participants

Reaction Steps

0.0388 cm3 of N-(3-aminopropyl)morpholine is added, at the same temperature, to a suspension of 150 mg of 3-({1-[bis(4-chlorophenyl)methyl]azetidin-3-ylidene}methanesulfonylmethyl)benzoic acid activated on TFP resin (165 μM) in 3 cm3 of dichloromethane, pre-stirred for 90 minutes at a temperature close to 20° C. The suspension is stirred at a temperature close to 20° C. for 22 hours and then filtered on sintered glass. The solid residue is rewashed with twice 1.5 cm3 of dichloromethane. The filtrates are combined and concentrated to dryness under reduced pressure (2.7 kPa) at a temperature close to 40° C. 60 mg of 3-({1-[bis(4-chlorophenyl)methyl]azetidin-3-ylidene}methanesulfonylmethyl)-N-(3-morpholin-4-ylpropyl)benzamide are thus obtained in the form of a pale yellow foam.
