実験手順

A solution of 1-(4-chlorobenzyl)-4-{(glycylamino)methyl)piperidine (0.050 mmol) in CHCl3 (1.35 mL) and tert-butanol (0.15 mL) was treated with 3-bromo-4-methylbenzoic acid (0.060 mmol), diisopropylcarbodiimide (0.060 mmol), and HOBt (0.060 mmol). The reaction mixture was stirred at room temperature for 15 h. The mixture was loaded onto Varian™ SCX column, and washed with CH3OH/CHCl3 1:1 (12 mL) and CH3OH (12 mL). Product was eluted off using 2 N NH3 in CH3OH (5 mL) and concentrated to afford 4-[{N-(3-bromo-4-methylbenzoyl)glycyl}aminomethyl]-1-(4-chlorobenzyl)piperidine (Compound No. 1113) (16.1 mg, 65%): The purity was determined by RPLC/MS (95%); ESI/MS m/e 494.0 (C23H27BrClN3O2).
