Triethylamine → Methyl 2-(1-methyl-3-(N-(4-octylphenyl)sulfamoylamino)piperidin-3-yl)acetate

Participants

Reaction Steps

A solution of 2-chloroethyl N-(4-octylphenyl)sulfamoylcarbamate (156 mg, 0.4 mmol) in CH3CN (10 mL) was treated with Et3N (0.14 mL, 1 mmol) and refluxed for 25 min. and cooled. A solution of 2-(3-amino-1-methylpiperidin-3-yl)acetate (62 mg, 0.33 mmol) was added and the resulting mixture was refluxed for 4 h. After removal of the solvent in vacuo, the residue was dissolved in dichloromethane (40 mL) and washed with sat. NaHCO3 (10 mL), H2O (10 mL), brine (10 mL) and dried (Na2SO4). After evaporation, the residue was purified by flash chromatography (EtOAc/hex 1:4 to EtOAc) to give the title compound (41 mg, 27%) as colorless oil. MS ESI 454.3[M+H]+, calcd for [C23H39N3O4S+H]+ 454.27.
