2-piperidin-4-ylbenzonitrile;hydrochloride

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 2-(1-tertbutoxycarbonylpiperidin-4-yl)benzonitrile (1.7 g, 5.9 mmol) in ethyl acetate (˜50 ml), cooled to 0° C. was added hydrogen chloride gas, bubbled vigorously for 5 minutes. The reaction mixture was stirred for 10 minutes at 0° C., purged with argon and concentrated. Flushing with ethyl acetate×3 and concentration gave 2-(piperidin-4-yl)benzonitrile hydrochloride; bubbled vigorously for 5 minutes purged with argon concentrated Flushing with ethyl acetate×3 and concentration

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.
