Versuchsvorschrift

Thionyl chloride (10 ml) was added to a solution of the title compound of Example 9 (9.7 g, 0.06 mole) in methyl alcohol (100 ml) cooled to 5° C. via an ice bath. The ice bath was removed and the reaction stirred for 2.5 hours at room temperature. The methyl alcohol and excess thionyl chloride were removed using a rotary evaporator to give 9.8 g, of an oil which was identified by NMR as the title compound.
