N-(1-benzylpiperidin-4-yl)benzamide

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a suspension of 10% palladium on carbon (0.2 g) in 30 mL of ethyl alcohol was added a solution of 1-benzyl-4-benzamido-piperidine (0.5 g, 1.79 mmol) in ethyl alcohol (10 mL). The resulting suspension was hydrogenated at 100 psi at 50° C. for 30 h after which it was filtered through a pad of celite and the solvent was removed in vacuo to obtain 0.34 g (100%) of 4-benzamidopiperidine as a white solid. It was used in the next step without purification. after which it was filtered through a pad of celite the solvent was removed in vacuo

Procedure: To a biphasic solution of 4-amino-1-benzylpiperidine (6.0 g, 31.6 mmol), K2CO3 (8.71 g, 63.1 mmol) in CH2Cl2 (200 mL) and water (100 mL) was added benzoyl chloride (4.86 g, 34.7 mmol) in 20 mL of CH2Cl2 at 0° C. with stirring. After stirring for 4 h at room temperature, the layers were separated. The organic layer was washed with water, dried over MgSO4 and filtered. The solvent was removed in vacuo to obtain 1-benzyl-4-benzamidopiperidine (8.16 g, 87% yield) as a white solid. It was used in the next step without purification. After stirring for 4 h at room temperature the layers were separated The organic layer was washed with water dried over MgSO4 filtered The solvent was removed in vacuo
