Reaction Steps

To 257 mg (1.04 mmol) 3-pyridin-2-ylmethyl-azetidine-1-carboxylic acid tert-butyl ester was added 2 mL DCM and 2 mL TFA. The mixture was stirred at room temperature for 30 minutes. The solvent was evaporated to give the desired product as a TFA salt, which was used in the next step without further purification.
