Procedure
A solution of 130 mg (0.412 mmol) 8-benzyl-1-(3-methyl-butyl)-1,3,8-triaza-spiro[4.5]decan-4-one in 2 ml methanol was debenzylated with hydrogen in presence of 30 mg 10% Pd/C at ambient temperature over night. Then the reaction mixture was filtered through a silica gel pad and the filtrate evaporated: 70 mg 1-(3-methyl-butyl)-1,3,8-triaza-spiro[4.5]decan-4-one as colorless solid: m.p. 103–105° C., MS (ISP): 226.3 MH+.
