A mixture of 1.8 g. (0.01 mole) of 3-amino-1-benzylpyrrolidine, 2.4 g. (0.01 mole) of 3,4,5-trimethoxybenzoyl azide, and 25 ml. of dry benzene was stirred 16 hours at room temperature followed by stirring for one hour at about 60°C. The mixture was cooled and 50 ml. of isopropyl ether added to the mixture. The crude crystalline product was separated by filtration and recrystallized from ethyl acetate-isopropyl ether mixture, giving 2.2 g. (60% yield). The melting point of the product after a second recrystallization from the same solvent was 128°-129°C.
