1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → [4-(Furan-2-carbonyl)piperazin-1-yl](4-{4-[4-(morpholine-4-sulfonyl)-phenyl]pyrimidin-2-ylamino}phenyl)methanone

반응 단계

4-{4-[4-(Morpholine-4-sulfonyl)-phenyl]-pyrimidin-2-ylamino}-benzoic acid (0.25 g, 0.57 mmol) was dissolved in THF (5 mL). To this solution was added 1-furoylpiperazine (0.123 g), EDCI (0.131 g), and HOBt (0.092 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 (20-70 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-(morpholine-4-sulfonyl)-phenyl]pyrimidin-2-ylamino}phenyl)methanone (0.177 g, 52%): HPLC Retention Time; 9.62 min. (Method B) M+H=603.3
