Reaction Steps

2.3 g (9.03 mmol) of methyl 3-(4-chlorophenyl)-3,4-dimethylpentanoate were dissolved in 50 ml of dichloromethane and cooled to 0° C. 1.44 g (10.8 mmol) of nitronium tetrafluoroborate were then added a little at a time. After the addition had ended, the reaction solution was initially stirred at 0°-10° C. for 1 h. The mixture was then slowly warmed to room temperature and stirred at this temperature for another 2 h. The reaction mixture was then added to about 50 ml of water, the phases were separated and the organic phase was dried over magnesium sulphate. The solution was concentrated by evaporation and the residue obtained was then purified by chromatography on silica gel (mobile phase cyclohexane/ethyl acetate 20:1). This gave 2.3 g (85% of theory) of the target compound.
