Procedure:
This compound was prepared according to the procedure described for the synthesis of Example 214 substituting 212b in place of 213c. Into a 8-mL sealed tube, was placed a solution of (S)—N1-(4-(diethylamino)-2-(4-(1,2,3,4-tetrahydronaphthalen-1-ylcarbamoyl)pyridin-2-yl)phenyl)-N3-methyl-N3-(2-(piperazin-1-yl)ethyl)isophthalamide (150 mg, 0.22 mmol, 1.00 equiv) in acetonitrile (5 mL), 2,5,8,11,14,17,20-heptaoxadocosan-22-yl 4-nitrophenyl carbonate (165 mg, 0.33 mmol, 1.50 equiv), 4-dimethylaminopyridine (53 mg, 0.43 mmol, 2.00 equiv). The resulting solution was stirred for 5 h at 90° C. in an oil bath. The resulting mixture was concentrated under vacuum. The resulting solution was diluted with 10 ml of water. The resulting solution was extracted with 3×30 mL of dichloromethane and the organic layers combined. The resulting mixture was washed with 3×30 mL of NH4Cl aq. The mixture was dried over anhydrous sodium sulfate and concentrated under vacuum. The crude product (100 mg) was purified by Prep-HPLC with the following conditions (1#-UV1-SHIMADZU-SPD-20A): Column, SunFire Prep C18, 19*150 mm 5 um; mobile phase, water with 0.05% TFA and CH3CN (30% CH3CN up to 50% in 6 min); Detector, Waters2545 UvDector 254&220 nm. 85.6 mg product was obtained. This resulted in 85.6 mg (28%) of (S)-2,5,8,11,14,17,20-heptaoxadocosan-22-yl 4-(2-(3-(4-(diethylamino)-2-(4-(1,2,3,4-tetrahydronaphthalen-1-ylcarbamoyl)pyridin-2-yl)phenylcarbamoyl)-N-methylbenzamido)ethyl)piperazine-1-carboxylate as a yellow solid.
