実験手順

To a suspension of cis-4-((E)-2-(4-fluorobenzoylimino)-6-((4-(2-hydroxypropan-2-yl)piperidin-1-yl)methyl)-2,3-dihydro-1H-benzo[d]imidazol-1-yl)cyclohexanecarboxylic acid (100 mg, 0.186 mmol) in DMF (3 mL) was added HATU (74.4 mg, 0.196 mmol) and DIPEA (0.036 mL, 0.205 mmol). The suspension was stirred for 15 minutes at RT. A solution of piperazine (161 mg, 1.863 mmol) in DMF (1 mL) was added, and the reaction was stirred at RT overnight. The reaction mixture was partitioned between water and EtOAc. The organic layer was concentrated and the residue purified by HPLC (15-90% ACN/0.1% TFA). The product fractions were combined, neutralized with saturated aqueous NaHCO3, and extracted with EtOAc (×2). The combined organic layers were washed with brine, dried over anhydrous magnesium sulfate, filtered, and concentrated to provide (E)-4-fluoro-N-(6-((4-(2-hydroxypropan-2-yl)piperidin-1-yl)methyl)-1-(cis-4-(piperazine-1-carbonyl)cyclohexyl)-1H-benzo[d]imidazol-2(3H)-ylidene)benzamide as a white powder (67 mg, 59.5% yield). MS, m/z (C34H45FN6O3): calcd, 604.3. found, 605.1 [M+H].
