Versuchsvorschrift

Sodium 6-((4-(4-(3-cyclobutylureido)-3-fluorobenzoyl)piperazin-1-yl)methyl)-picolinate (100 mg, 0.209 mmol), triethylamine (66 mg, 0.693 mmol, 0.091 mL) and tert-butylamine (32 mg, 0.435 mmol) were combined and stirred at room temperature in dichloromethane. 1-Propanephosphonic acid cyclic anhydride (208 mg, 0.326 mmol, 0.194 mL, 50% solution in ethyl acetate) was added dropwise and the reaction allowed to stir for 1 hour. The reaction mixture was concentrated at reduced pressure, the resulting residue taken up in ethyl acetate and washed with saturated sodium bicarbonate solution. The organic phase was dried over sodium sulfate and concentrated under vacuum to afford the title compound (24 mg). MS (ESI) m/z 511.6 [M+H]+
