Versuchsvorschrift

A 4 N hydrochloric acid/ethyl acetate solution (3.90 mL, 15.6 mmol) was added to a solution of tert-butyl 3-({[(benzyloxy)carbonyl]amino}methyl)azetidine-1-carboxylate obtained in Example (233a) (560 mg, 1.75 mmol) in 1,4-dioxane/methanol (8 mL/8 mL), and the mixture was stirred at room temperature for 4.5 hours. The reaction solution was concentrated to obtain 448 mg of 3-({[(benzyloxy)carbonyl]amino}methyl)azetidine hydrochloride (100%).
