실험 절차

To a solution of 2-[(4-[4-nitro-3-(trifluoromethyl)phenyl]aminocyclohexyl)-oxy]acetic acid (173 mg, 0.48 mmol, 1 eq) in dichloromethane (50 ml) was added DIEA (61.8 mg, 0.48 mmol, 1 eq), HATU (182 mg, 0.48 mmol, 1 eq) and 1-(6-fluoronaphthalen-2-yl)piperazine (110 mg, 0.48 mmol, 1 eq) at room temperature under an inert atmosphere of nitrogen. The resulting solution was stirred overnight. The reaction was then quenched by the addition of water (100 ml) and extracted with dichloromethane (3×50 ml) and the organic layers were combined and then dried over anhydrous sodium sulfate. The solids were filtered off. The resulting mixture was concentrated under vacuum to give a residue, which was applied onto a silica gel column and eluted with 2% methanol in dichloromethane. The product-containing fractions were combined and concentrated under vacuum to afford 1-[4-(6-fluoronaphthalen-2-yl)piperazin-1-yl]-2-[(4-[[4-nitro-3-(trifluoromethyl)phenyl]amino]cyclohexyl)oxy]ethan-1-one as a yellow solid (31.1 mg, 11%); (ES, m/z): [M−H]− 573.2; 1H NMR (300 MHz, DMSO/D2O): δ 8.05 (d, J=6.9 Hz, 1H), 7.77-7.82 (m, 2H), 7.53-7.56 (dd, J=1.8, 7.5 Hz, 1H), 7.43-7.46 (dd, J=1.5, 6.9 Hz, 1H), 7.28-7.33 (m, 1H), 7.25 (d, J=1.2 Hz, 1H), 7.06 (s, 1H), 6.83-6.86 (dd, J=1.8, 6.9 Hz, 1H), 4.21 (s, 2H), 3.63 (broad s, 4H), 3.37-3.52 (m, 2H), 3.21-3.26 (m, 4H), 1.94-2.05 (m, 4H), 1.34-1.39 (m, 2H), 1.23-1.29 (m, 2H).
