Participants

Reaction Steps

To a mixture of 16-(3-(4-(diethylamino)-2-(4-(3-(trifluoromethyl)benzylcarbamoyl)pyridin-2-yl)phenylcarbamoyl)phenyl)-4,7,10,13-tetraoxahexadecan-1-oic acid (292 mg, 0.36 mmol), tert-butyl piperazine-1-carboxylate (75 mg, 0.40 mmol) and DIPEA (142 mg, 1.1 mmol) in DMF (3 mL) was added HATU (160 mg, 0.42 mmol). After 30 minutes, the solvent was removed under vacuum and the residue was dissolved in DCM (50 mL). This was washed with water (4×25 mL), dried (Na2SO4) and concentrated. The resulting oil was dissolved in DCM (2 mL) and TFA (2 mL) was added dropwise. After 30 minutes, the solvents were removed under vacuum. The residue was dissolved in 50% ACN/water (30 mL) and freeze dried to give the title compound (560 mg) as a TFA salt.
