4.5 g (0.035 mol) of N,N-dimethyl-3-oxobutyramide, a solution of 4.9 g (0.122 mol) of NaOH in 45 ml of water and 0.037 mol of phenyldiazonium chloride were treated as described in preparation 8. The crude reaction mixture was purified by chromatography on silica gel (hexane/Et2O 0%→100%) obtaining 3.5 g of the title compound which was used as such in the subsequent step. M.p.=131°-133° C.
