6-Azaindole (4.48 g, 37.9 mmol) was dissolved in MeOH (70 mL) and KOH (4.68 g, 83.4 mmol) and tert-butyl 4-oxopiperidine-1-carboxylate (8.31 g, 41.7 mmol) were added. The reaction mixture was heated at 70° C. for 18 h. The residue was partitioned between water (250 mL) and DCM (250 mL) and the aq phase was extracted with DCM (2×250 mL). The combined organic fractions were dried (MgSO4) and concentrated in vacuo to give the title compound as a yellow foam (11.3 g, 99%). LCMS (ES+): 300.1 [MH]+.
