Chloroform → 1-(4-chlorobenzyl)-4-[[N-(3,5-bis(trifluoromethyl)benzoyl)glycyl]aminomethyl]piperidine

A dichloromethane (1 mL) solution of 3,5-bis(trifluoromethyl)benzoyl chloride (0.058 mmol) was added to a mixture of 1-(4-chlorobenzyl)-4-[(glycylamino)methyl]piperidine (0.050 mmol) with chloroform (0.2 mL), a piperidinomethylpolystyrene (58 mg) and dichloromethane (0.75 mL). The resulting reaction mixture was stirred at room temperature for 2 hours, and methanol (1.0 mL) was then added to the obtained mixture. The resulting mixture was stirred at room temperature for 30 minutes. The reaction mixture was loaded onto a Varian™ SCX column and washed with methanol (16 mL). The obtained crude product was eluted with a 2 M methanol solution of NH3 (6 mL) and concentrated to thereby provide 1-(4-chlorobenzyl)-4-[[N-(3,5-bis(trifluoromethyl)benzoyl)glycyl]aminomethyl]piperidine (Compd. No. 1213) (24.0 mg, 90%). The purity was determined by RPLC/MS (100%). ESI/MS m/e 536.2 (M++H, C24H24ClF6N3O2).
