Reaction Steps

To 41.5 mg (0.17 mmol) 3-pyrazol-1-ylmethyl-azetidine-1-carboxylic acid tert-butyl ester was added 2 mL of 25% TFA in DCM and the reaction was stirred at room temperature for 1 hour. The solvent was evaporated to give the desired product as a TFA salt, which was used in the next step without further purification.
