Procedure

4-{4-[4-(4-Hydroxybutylsulfanyl)phenyl]pyrimidin-2-ylamino}benzoic acid (0.34 g, 0.86 mmol) was dissolved in THF (5 mL). To this solution was added 1-furoylpiperazine (0.170 g), EDCI (0.180 g), and HOBt (0.127 g). The mixture was stirred 12 h. The mixture was then diluted with CH2Cl2 (20 mL) and washed with 2% NaOH (aq, 30 mL), water (30 mL), and then brine (30 mL). The organic layer was dried (Na2SO4), filtered, and concentrated. The crude solid was subjected to preparatory HPLC (30–80 acetonitrile/water gradient, 20 min). The desired fractions were concentrated to remove most of the acetonitrile, and then the aqueous mixture was extracted with CH2Cl2/2% NaOH (aq). The organic layer was dried (Na2SO4), filtered, and concentrated to afford [4-(Furan-2-carbonyl)-piperazin-1-yl]-(4-{4-[4-(4-hydroxybutylsulfanyl)phenyl]pyrimidin-2-ylamino}phenyl)methanone (0.042 g, 9%): HPLC Retention Time; 10.07 min. (Method B) M+H=558.3.
