Ammonium formate → 4-Benzo[1,3]dioxol-4-yl-piperidine

Participants

Reaction Steps

Pd/C 10% (169 mg, 159 μmol,) was added to a solution of 4-(benzo[1,3]dioxol-4-yl)-1,2,3,6-tetrahydropyridine hydrochloride (760 mg, 3.17 mmol) and ammonium formate (1.00 g, 15.9 mmol) in methanol (28.8 ml) under argon. After refluxing for 60 min the reaction mixture was cooled to room temperature, filtrated and concentrated under reduced pressure. Saturated sodium bicarbonate solution was added to the residue and the mixture was extracted with dichloromethane (3×25 mL). The organic layers were dried over MgSO4 and concentrated in vacuo to yield the title compound as a white solid (0.654 grs, 100%). MS (ISP) m/z=206.0[(M+H)+].
