Diisopropyl azodicarboxylate (1.17 mL, 6.04 mmol) was added to a THF (15 mL) solution of tert-butyl 3-(hydroxymethyl)piperidine-1-carboxylate (1 g, 4.64 mmol), phthalimide (888 mg, 6.04 mmol), and triphenylphosphine (1.58 g, 6.04 mmol), and the mixture was stirred at room temperature for 24 hours. The reaction mixture was concentrated under reduced pressure, and the resulting residue was purified using silica gel column chromatography to obtain the target (1.45 g, 90%).
