Versuchsvorschrift

To 3.0 g of product from Example 131 in 30 ml of methylene chloride plus 2 drops of dimethylformamide is added 2.0 ml of oxalyl chloride via syringe. The reaction is stirred at room temperature for 18 hours, concentrated in vacuo, dissolved in diethyl ether and filtered through a pad of diatomaceous earth. The diethyl ether is concentrated in vacuo to give 3.15 g of the desired product as a yellow oil.
