Participants

Reaction Steps

Ethyl (RS)-2-(1,1-dimethylethyl)-4-oxo-butanoate (0.57 g) was dissolved in excess triethylorthoformate and a catalytic amount of p-toluenesulphonic acid was added. After stirring for 1 hour at the ambient temperature, excess triethylorthoformate was evaporated under reduced pressure to give ethyl (RS)-4,4-diethoxy-2-(1,1-dimethylethyl)butanoate, the spectral data of which were identical to those obtained in Example 6 (ii).
