N,N-Dimethylformamide was evaporated at 40° C./0.1 mbar, the residue was extraced with dichloromethane and 10% Na2CO3, and then purified by chromatography on silica gel in dichloromethane/methanol 20:1. One obtained a yellow oil which was triturated with ethyl acetate, and the resulting white crystals were filtered off. One obtained 191 mg (54%) of white crystals. MS: m/z=447 (M+H).
