Procedure

tert-Butyl 1H-pyrrolo[2,3-c]pyridine-1-carboxylate (1.0 g, 4.58 mmol) and PtO2 (0.208 g, 0.916 mmol) were placed in 1:1 EtOH:AcOH (10 mL) and shaken at 50 PSI under H2 for 8 hours. The reaction was then concentrated. The crude oil was dissolved in DCM, poured into saturated Na2CO3 and extracted into DCM. The organic fraction was dried, filtered, and concentrated to give the product as an oil, tert-butyl octahydro-1H-pyrrolo[2,3-c]pyridine-1-carboxylate (0.99 g, 95.5% yield).
