Morpholine → 2-(1-Naphthylmethylene)-3-(morpholinocarbonyl)propionic acid

Participants

Reaction Steps

The solution of 1.00 g of the 2-(1-naphthylmethylene)succinic anhydride and 0.37 g of morpholine in 31 ml of dry dichloromethane was stirred for 2 hours at room temperature. The reaction mixture was evaporated under reduced pressure, and the residue was triturated with a mixture of ethyl acetate, benzene and hexane (1/1/1 by volume) to obtain 1.10 g of 2-(1-naphthylmethylene)-3-(morpholinocarbonyl)propionic acid as colorless crystals.
