Participants

Reaction Steps

A mixture of 4-[{N-(2-amino-5-bromobenzoyl)glycyl}aminomethyl]-1-(4-chlorobenzyl)piperidine (25 mg, 0.05 mmol), methanesulfonyl chloride (0.0045 mL), triethylamine (0.026 mL) and dichloromethane (2 mL) was stirred at room temperature for 17 h. The reaction mixture was purified with column chromatography (SiO2), loaded onto Varian™ SAX column, and washed with CH3OH (5 mL). Product was eluted off using 0.1 N HCl in CH3OH (5 mL) and concentrated to afford 4-[{N-(5-bromo-2-(methylsulfonylamino)benzoyl)glycyl}aminomethyl]-1-(4-chlorobenzyl)piperidine (Compound No. 1581) (5.4 mg, 19%): ESI/MS m/e 573.0 (M++H, C23H28BrClN4O4S).
