Versuchsvorschrift

3 g (0.0146 mole) of dicyclohexylcarbodiimide (DCC) was added to the solution of 4.48 g (0.0112 mole) of 1-amino-polyethylene glyco (molecular weight 400), 3.98 g (0.0133 mole) of retinoic acid and 1.51 g (0.0112 mole) of 1 -hydroxybenzotriazole in 40 ml of dry dichloromethane, and the reaction solution was then treated according to the same procedure as described in Example 1(A) to obtain the title compound (Yield 62%, Tm=−14° C., Rf=0.15).
