Procedure
A solution of [1-(5-benzyl-5-azaspiro[2.4]hept-7-yl)ethyl]carbamic acid tert-butyl ester (Example A4a, 1.47 g) in methanol (30 mL) in a Parr shaker is treated with 10% palladium on carbon (0.5 g) and hydrogen introduced (50 psi) for 24 hours. The reaction mixture is filtered through celite, washed with methanol, and the combined filtrate concentrated in vacuo to afford the title compound. MS CI: m/z 241 (MH+).
