Reaction Steps

A solution of oxalyl chloride (36.5 g, 0.29 mol) in dry benzene (50 ml) was added dropwise to a stirred solution of compound 24 (25.5 g, 0.14 mol) and dry DMF (40 drops) in dry benzene (500 ml) at room temperature. The mixture was stirred at room temperature overnight and the excess of oxalyl chloride and benzene were removed in vacuo.
