Procedure

The preparation is carried out as described in Example 1, using 44.8 g (0.2 mole) of dibenzoyl methane, 61.0 g (0.2 mole) of n-hexadecyl chloroformate and 200 ml of diethyl ether as well as 22 g (0.22 mole) of triethylamine. The resultant yellow viscous liquid crystallises out. The crystals melt at 39°-40° C.
