Participants

Conditions

Temperature: 25 °C

Procedure

TFA (2 ml) was added to a solution of tert-butyl 8-(pyridine-3-yl)-2,8-diazaspiro[4.5]decane-2-carboxylate (1.14 mmol, 1.0 eq.) in methylene chloride (6 ml) at 0° C. and the reaction mixture was stirred at 25° C. for 2 h. When the reaction was complete, the solvent was concentrated in vacuo in order to obtain the desired amine (AMN-24).
