Procedure

Finely ground K2CO3 (54 mg, 039 mmol) was added to a solution of 2-(5-(diethylamino)-2-(3-(16-(4-(4-hydroxyphenyl)piperazin-1-yl)-16-oxo-4,7,10,13-tetraoxahexadecyl)benzamido)phenyl)-N-(3-(trifluoromethyl)benzyl)isonicotinamide (125 mg, 0.13 mmol) and 2-(2-(2-methoxyethoxy)ethoxy)ethyl 4-methylbenzenesulfonate (50 mg, 0.16 mmol) in DMF (0.30 mL), and was heated at 70° C. for 3 hours with stirring. The reaction mixture was cooled to room temperature and another portion of 2-(2-(2-methoxyethoxy)ethoxy)ethyl 4-methylbenzenesulfonate (75 mg, 0.34 mmol) was added. The mixture was stirred for 3 days at room temperature and then 5 hours at 70° C. Water (10 mL) was added to the cooled reaction mixture and extracted with DCM (3×10 mL). The combined organic layers were dried (Na2SO4) and concentrated. Purification by reverse-phase HPLC eluting with a water/ACN gradient containing 0.1% TFA gave a TFA salt of the title compound (80 mg). 1H NMR (400 MHz, CD3OD, ppm) δ 9.44 (t, J=5.0 Hz, 0.6H), 8.93 (dd, JAB=5.3 Hz, JAC=0.6 Hz, 1H), 8.84 (d, J=9.0 Hz, 1H), 8.40 (s, 1H), 8.09 (d, J=2.5 Hz, 1H), 7.88 (dd, JAB=5.1 Hz.
