Versuchsvorschrift

A solution of 99 g of phosgene (1 mole) in 800 ml of anhydrous toluene was cooled beneath 15° C. While the reaction mixture was cooled and stirred a solution of 131 g of methylindolizine (1 mole) in 475 ml of anhydrous toluene was added dropwise. The reaction mixture was kept overnight and the residue formed was sucked off.
