Reaction Steps

100 mg of [1-(5-carbamoyl-4-{(1R)-1-[2-(trifluoromethyl)phenyl]ethoxy}-2-thienyl)-1H-imidazo[4,5-c]pyridin-6-yl]methyl methanesulfonate and 205 mg triethylamine are dissolved in 2.5 ml dichloromethane. Under N2 atmosphere 1-cyclopropylpiperazine dihydrochloride (184 mg) is added. The reaction mixture is stirred at 40° C. for 1 hour and then concentrated to dryness under vacuum. The residue is purified by preparative HPLC (ammonium formate buffer/acetonitrile, elution gradient 97/3 to 0/100 (v/v)) to obtain the title product.
