The reaction mixture was then filtered through kieselguhr, the filter cake was washed with ethanol and the filtrate was concentrated. The residue was triturated with ethanol at 50° C., and the solid was filtered off and dried under high vacuum. This gave 107 mg (58% of theory) of the title compound.
