Procedure

To a room temperature suspension of 15 g of product from Example 2, 160 ml methylene chloride and 5 drops dimethylformamide is added 5.87 ml oxalyl chloride. The reaction mixture is stirred at room temperature for 18 hours, concentrated in vacuo, dissolved in 300 ml of diethyl ether, filtered through diatomaceous earth and the filtrate concentrated in vacuo to give 15.5 g of the desired product.
