Procedure

A mixture of tert-butyl {[3-(dibenzylamino)oxetan-3-yl]methyl}carbamate (13.0 g, crude), 20% palladium hydroxide on carbon (2.0 g) and trifluoroacetic acid (0.5 mL) in methanol (20 mL) was stirred overnight under hydrogen atmosphere (1 bar). After being basified with ammonia solution in methanol, the resulting mixture was filtered and concentrated in vacuo to afford 5.8 g of the crude product, which was used for the next step without any purification.

Workup

  1. filtrationthe resulting mixture was filtered
  2. concentrationconcentrated in vacuo
