After cooling, the solid obtained was filtered off with suction and washed with methyl tert-butyl ether. The solid was then dissolved in a mixture of dichloromethane and tetrahydrofuran, washed with saturated aqueous sodium bicarbonate solution, dried and concentrated under reduced pressure. This gave 5.9 g of the title compound. LC/MS (Method LC1): Rt=1.24 min; m/z=318.08 [M+H]+
