Reaction Conditions

Reaction Steps

To 4.25 g (18.5 mmol) rac-4-cyclohexyl-4-nitro-butyric acid methyl ester were added 4.56 ml (32.5 mmol) 1,3,5-trimethylhexahydro-1,3,5-triazine and the mixture heated to 100° C. for 4 hours. The reaction mixture was cooled to ambient temperature and adsorbed on silica gel which was transferred on top of a silica gel column and purified by flash-chromatography with a gradient of heptane and 10 to 75% ethyl acetate: 2.55 g of title compound were isolated as colourless oil: MS (m/e): 240 (MH+).
