Reaction Steps

A mixture of N-(3′-hydroxy-biphenyl-4-yl)guanidine (550 mg), 2,4-dichloropyrimidine (146 mg) and potassium carbonate (196 mg) in DMF (8 ml) is stirred at rt for 20 h. This mixture is purified by preparative HPLC (gradient of water, 0.1% TFA/acetonitrile, 0.1% TFA from 80/20 to 0/100 on Nucleosil 100-10 C18 column). The fractions containing product are basified with 1 N NaOH to pH 8, evaporated and dried under reduced pressure. The residue is stirred in ethanol, the solvent is evaporated and dried under reduced pressure to afford crude N-[3′-(2-chloro-pyrimidin-4-yloxy)biphenyl-4-yl]-guanidine.
