Versuchsvorschrift
194 g of diphenyl carbodiimide, 31 g of ethylene glycol and 0.05 g of Sn(II)-(2-ethyl hexoate) are dissolved in 200 g of xylene. The reaction solution is heated to reflux temperature, diphenyl urea being precipitated. Concentration of the xylene solution gives 102 g (86% of the theoretical) of 2-phenyl imino-3-phenyl oxazolidine. Mp: 115° to 117° C.
