Procedure: A mixture of 5.68 parts of 1,3-dihydro-1-(3-hydroxypropyl)-5-methyl-2H-benzimidazol-2-one methanesulfonate, 4.62 parts of 1-phenyl-1,3,8-triazaspiro[4,5]decan-4-one, 3.7 parts of sodium carbonate and 45 parts of N,N-dimethylformamide is stirred for 1 hour at 60° C. The reaction mixture is cooled and poured onto water. The precipitated product is filtered off and purified by column-chromatography over silica gel using a mixture of trichloromethane and 10% of methanol as eluent. The pure fractions are collected and the eluent is evaporated. The residue is crystallized from a mixture of N,N-dimethylformamide and water, yielding 2 parts (24%) of 8-[3-(1,3-dihydro-5-methyl-2-oxo-2H-benzimidazol-1-yl)propyl]-1-phenyl-1,3,8-triazaspiro[4,5[decan-4-one; mp. 255.5° C. The reaction mixture is cooled poured onto water The precipitated product is filtered off purified by column-chromatography over silica gel using a mixture of trichloromethane and 10% of methanol as eluent The pure fractions are collected the eluent is evaporated The residue is crystallized from a mixture of N,N-dimethylformamide and water

Procedure: 24.76 g (158 mmol) of 4-decanone and 20.94 g (158 mmol) of tert-butyl carbazate are heated for 90 minutes at 80° C. in 250 ml of cyclohexane/heptane mixture (1:1). After cooling, 39.71 g (93%) of a white solid are obtained by crystallization. After cooling

Procedure: The procedure of Example 1 was repeated, except that a mixture of 1-decanol (0.5 millimole) and 4-decanol (0.5 millimole) was used instead of 1-decanol, to give 1-decanal (yield 83%), and 4-decanone (yield 3%).
