Procedure

To a solution of 8-(2-Methyl-5-nitro-phenyl)-1,4-dioxa-8-aza-spiro[4.5] decane (100 mg, 0.278 mmol) in the mixed solvent of THF (3 ml) and methanol (3 ml) was added 10% Pd/C, and the reaction mixture was stirred for 12 hours at room temperature under a hydrogen balloon. The reaction mixture is filtered and the filtrate was concentrated under vacuum to give 3-(1,4-Dioxa-8-aza-spiro[4.5]dec-8-yl)-4-methyl-phenylamine [29] (Yield: 84.9 mg, 95.2%) as a off white solid.
