In a 100 ml round-bottom flask 1.63 g (5.01 mmol) of tert-butyl 4-(1-(oxetan-3-yl)-piperidin-4-yl)-piperazine-1-carboxylate were dissolved in 5 ml of dichloromethane. 3 ml (38.9 mmol) of trifluoroacetic acid were added and the reaction was stirred for 30 min. The solution was concentrated and digested in 40 ml of methyl-tert-butyl ether. The solid was filtered and washed with 20 ml of methyl-tert-butyl ether to yield 2.79 of the title compound as a white solid.
