Versuchsvorschrift
A mixture of 0.89 g (0,002 mole) of the compound from Example 31, 0.69 g (0.003 mole) of 4-carbomethoxybenzyl bromide (Aldrich), 5.0 g of powdered anhydrous sodium carbonate, and 5 mL of DMF is heated at reflux, with stirring, for 5 minutes. The cooled mixture is treated with 50 mL of ice water. The precipitated product is extracted into 150 mL of ether. The solution is dried (magnesium sulfate) and concentrated; wt. of amorphous solid 1.20 g; mass spectrum (CI) 594 (M+).
