Procedure

A solution of 32-azido-3,6,9,12,15,18,21,24,27,30-decaoxadotriacontan-1-amine (436.9 mg, 0.777 mmol) in dry DMF (3.5 mL) under N2 was cooled to 0° C. A solution of 3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzene-1-sulfonyl chloride (300 mg, 0.706 mmol) and DIEA (273.2 mg, 2.118 mmol) in DMF (3 mL) was added dropwise. After 60 minutes LCMS indicated complete conversion and the solvent was removed to give N-(32-azido-3,6,9,12,15,18,21,24,27,30-decaoxadotriacontyl)-3-(6,8-dichloro-2-methyl-1,2,3,4-tetrahydroisoquinolin-4-yl)benzenesulfonamide (620 mg) as a yellow oil which was used without further purification.
