Participants

Reaction Steps

(R)-1,1,1,3,3,3-Hexafluoro-2-(4-((3-methylpiperazin-1-yl)methyl)phenyl)propan-2-ol (0.427 mmol, 0.152 g), 4-(3-(cyclopropylmethyl)ureido)benzoic acid (0.427 mmol, 0.1 g) and triethylamine (1.281 mmol, 0.178 mL, 0.130 g) were combined in dichloromethane and stirred at room temperature. 1-Propanephosphonic acid cyclic anhydride (0.640 mmol, 0.381 mL, 0.407 g; 50% solution in ethyl acetate) was added and the reaction allowed to stir for 1 hour. The reaction mixture was washed with saturated sodium bicarbonate solution, dried over sodium sulfate and concentrated under vacuum. The resulting residue was purified by silica chromatography (eluting with a solvent gradient from dichloromethane to 5% methanol/dichloromethane) to afford the title compound (38 mg).
