실험 절차

To a mixture of 50 g of product from Example 42 in 500 ml of methylene chloride and 15 drops of dimethylformamide is added, dropwise, 26.12 g of oxalyl chloride. The reaction is stirred at room temperature for 18 hours and concentrated in vacuo. The residue is recrystallized from diethyl ether to give 52.3 g of the desired product as white crystals.
