The reaction was then concentrated, and the crude oil was dissolved in DCM and poured into saturated Na2CO3 and extracted into DCM. The combined organic fractions were dried, filtered, and concentrated to give tert-butyl octahydro-1H-pyrrolo[2,3-c]pyridine-1-carboxylate (0.99 g, 95% yield) as an oil.
