Piperidine → HCID 18426242, compound

Participants

Reaction Steps

Piperidine (0.048 mmol), diisopropylcarbodiimide (0.45 mmol) in DMF (0.15 mL), 1-hydroxybenzotriazole hydrate (0.45 mmol) in DMF (0.15 mL) were added to a solution of 1-(4-carboxybenzyl)-4-[{N-(3-(trifluoromethyl)benzoyl)glycyl}aminomethyl]piperidine (0.040 mmol) in DMF (1.0 mL). The reaction mixture was stirred at room temperature for 17 h, loaded onto Varian™ SCX column, and washed with CHCl3/CH3OH 1:1 (5 mL) and CH3OH (5 mL). Product was eluted off using 2 N NH3 in CH3OH (5 mL) and concentrated to afford 1-{4-(piperidinocarbonyl)benzyl}-4-[{N-(3-(trifluoromethyl)benzoyl)glycyl}aminomethyl]piperidine (Compound No. 1572) (14.3 mg, 66%): The purity was determined by RPLC/MS (99%); ESI/MS m/e 545 (M++H, C25H35F3N4O3).
