Procedure

To a mixture of 50.0 g of product from Example 37 in 700 ml of chloroform and 10 drops of dimethylformamide is added, dropwise, 25.8 g of oxalyl chloride. The reaction is stirred at room temperature for 18 hours and concentrated in vacuo. The residue is dissolved in diethyl ether, filtered and concentrated in vacuo to give 51.1 g of the desired product as white crystals.
