After stirring at RT for 2 h, the mixture was heated to 50° C. for 4 h and left to stand over the weekend. Then the DMF was drawn off and the residue was taken up in EA. The EA phase was washed with water, dried, filtered and concentrated. The crude product was purified using silica gel (100 g, n-heptane/EA 4:1). 813 mg of the title compound were obtained.
