実験手順
2.2 g (7.8 mmol) of the title compound from Example 3 are dissolved in 50 ml of anhydrous dichloromethane and a solution of 2 ml of thionyl chloride in 6 ml of dichloromethane is added dropwise at -10° C. The mixture is warmed to room temperature, stirred for 30 minutes more, and concentrated. The crystalline residue is brought to crystallization using diisopropyl ether and dried using an oilpump, m.p. 133°-135° C.
